Fork Feature Gaps

Features and fixes that other PS2 loaders, forks and launchers have and RiptOPL does not have yet. Each entry was checked against RiptOPL's own code rather than taken from another project's changelog, and links to where that project implements it.

ℹ A tracking list, not a roadmap

An entry here means another project has something RiptOPL does not; it does not mean the feature is scheduled. Checked on 2026-09-14 against rebuild/main at 3f2e9b1d, and updated on 2026-09-15 when PR #658 shipped three entries (see Notes). Every entry has a short ID whose letter names its source (see Sources surveyed), so it can be referenced in issues and chat. Entries in the Beyond game loading area are general-purpose tools from PS2 environments built on OPL, listed so the survey is complete.

wOPL

ps2homebrew/wOPL — much of RiptOPL's Coverflow, Favorites and Neutrino work started here. These are the parts RiptOPL does not have yet.

ID	Feature	What it does	Source
`W1`	Themes loaded from a `.tar` archive	Several themes packed into `THM/thm.tar`, with fonts and images read straight from the archive.	PR #370 PR #378
`W2`	`wsX` widescreen X position	A separate X coordinate per element for 16:9, so one theme file serves both 4:3 and widescreen.	src/themes.c
`W3`	PADEMU, GSM and cheat status icons	On/off images showing each game's pad emulation, GSM and cheat settings, with built-in default images.	src/textures.c src/themes.c
`W4`	Disc art toggle without restart	An Enable Disc Art setting that takes effect immediately. RiptOPL has no disc art toggle.	PR #308
`W5`	Held scrolling stalls every ~29 seconds Fix	The pad timer wraps roughly every 29 seconds; when it does, a held direction stops repeating until the button is released.	PR #308
`W6`	Info page without list navigation Optional	Up, down and page buttons no longer move through the list from a game's info page. A design choice rather than a missing capability.	PR #308

OPLattice

coffeedevsolutions/OPLattice — nine patches to OPL's theme engine and menus, a sidebar interface, themes and PC tooling.

ID	Feature	What it does	Source
`O1`	Grid game list	A tile layout for the game list (`columns`, `cell_width`, `gap`, `frame`) with two-axis navigation.	patch 01
`O2`	`GameImage offset` for non-selected games	An image element can draw the game a set number of places down the page, which makes hero and filmstrip layouts possible.	patch 01
`O3`	Recently played list	The last 8 games launched, newest first, shown with `RecentImage` and `RecentText` elements. RiptOPL remembers only the last one.	patch 02
`O4`	Sort modes	A to Z, Z to A, most recent first, or as scanned. OPLattice cycles them with R3, which RiptOPL uses for Favorites.	patch 02
`O5`	`MenuTabs` device tab strip	Every device drawn at once with the active one highlighted, plus per-device label overrides.	patch 03
`O6`	`GameCountText` prefix and suffix	Themes set their own wording around the game count.	patch 03
`O7`	`x_scaled` widescreen alignment	Elements keep their position relative to a centred layout when widescreen is on.	patch 03
`O8`	VRAM texture budget clamp Fix	Caps texture size to the video memory left after the framebuffers, so an oversized theme image is rejected instead of risking a hang in hi-res modes.	patch 07
`O9`	Play stats	A launch count and playtime for each game.	patch 08
`O10`	SHELF sidebar interface	An opt-in sidebar with Home, Library, Apps and Settings pages. It opens with L3, which RiptOPL uses to switch between PS2 and PS1 views.	patch 09
`O11`	App subtitles	An optional `subtitle` key in an app's `title.cfg`.	patch 09
`O12`	Art conversion and VRAM checker Tool	Converts art to indexed PNG8 and reports how much memory each theme's art cache will use.	palettize-art.py check-art.py
`O13`	In-game screenshot importer Tool	Turns in-game screenshot BMPs from the memory card into the `_SCR.png` images the info page shows.	import-igs.py
`O14`	Browser theme previewer Tool	A single HTML file that renders a theme's layout before it goes on a console.	opl-theme-previewer.html
`O15`	Device staging and card sync scripts Tool	Scripts that copy a build onto a USB device or HDD and sync a memory card.	tools/

Upstream OPL pull requests

ps2homebrew/Open-PS2-Loader — RiptOPL is built on upstream's master branch, so the gaps here are pull requests not yet merged there.

ID	Feature	What it does	Source
`U1`	Per-game parental lock	A Parental Lock toggle in a game's settings; starting that game asks for the parental lock password.	PR #1779
`U2`	Remembered per-game cheat selections	Saves which optional cheats were enabled for each game, by cheat name, with master codes always on.	PR #1748
`U3`	Disc size from the real media Fix	Out-of-bounds read checks use the image's real sector count instead of the ISO volume field, so discs mastered with a short volume (Zombie Zone, Demolition Girl) boot again. RiptOPL still reads the volume field.	PR #1763
`U4`	In-game reset without the VBLANK interrupt Fix	Checks the in-game reset button combo from a timer instead of the VBLANK handler; titles that black-screened with the old hook boot, and in-game reset still works.	PR #1762
`U6`	Launch announcement for Discord rich presence	When a game starts, a small UDP broadcast carries its title ID so a PC listener can set Discord rich presence.	PR #1736
`U9`	Bluetooth controller input lag Investigate	Shortens PADEMU Bluetooth polling delays to remove input lag. As submitted it also turns off rumble and the menu's pad delay, so it is a lead rather than a finished fix.	PR #1675

BoliviaOS

boliviaos.site — an OPL-based environment that adds file management, media and system tools around game loading. Its source is not published, so these entries come from the features its site lists.

ID	Feature	What it does	Source
`B1`	File explorer	Browse and move files across memory cards, USB, HDD and host from inside the loader, with transfers checked against the source.	boliviaos.site
`B2`	Music player	Plays MP3 and OGG files with ID3 tags and a spectrum visualizer.	boliviaos.site
`B3`	Image and font viewers	Views JPG and PNG images with zoom and transparency inspection, and TrueType fonts with Unicode coverage.	boliviaos.site
`B4`	Text editor, code editor and terminal	Edits `.txt` and `.cfg` files, with a JavaScript editor and a command terminal.	boliviaos.site
`B5`	Memory card format and repair	Low-level memory card formatting and repair through Memory Card Annihilator.	boliviaos.site Memory Card Annihilator
`B6`	USB keyboard	USB HID keyboard input.	boliviaos.site
`B7`	PDF viewer	Reads PDF documents. The site lists it as still in development.	boliviaos.site

PS2-Launcher

Irfanlesnar/PS2-Launcher — an OPL-based launcher with a console-style interface. Checked against its published v4.0 source, not only its README.

ID	Feature	What it does	Source
`P1`	Xbox One and Series controllers over USB	Wired Xbox controllers through a new IOP driver. RiptOPL supports DualShock 3, DualShock 4 and DualSense.	modules/xboxusb
`P2`	Download covers from the PS2	Fetches missing covers, or refreshes all of them, over the network from the console.	src/opl.c PS2-Launcher-Manager
`P3`	One games list across every device	A single Games list combining every connected source, part of its console-style interface.	src/opl.c
`P4`	Hold SELECT to leave a game	Holding SELECT for 7–10 seconds in a game returns to the launcher, an alternative to the multi-button in-game reset combo.	ee_core/src/padhook.c
`P5`	Launch transition animation	An animated transition as a game starts. OPL-Evolution adapted it too.	src/opl.c

Project Titan

sobecapaklebs-dev/project-titan-magenta-edition — a PS2 system shell and application platform whose game launching is one subsystem among many.

ID	Feature	What it does	Source
`T1`	Graphics patches kept apart from cheats	Graphics patches such as widescreen live in `ENH/<id>.enh`, separate from gameplay cheats in `CHT/`, and the selection is remembered per game. See Cheats for what RiptOPL reads today.	TITAN_GAME_PATCHES.md
`T2`	Installable app packages and runtime	Installable packages and an application runtime, so native apps run as part of the system instead of as separately launched ELFs.	README

OPL-Evolution

officialjuicedesigns/OPL-Evolution — an experimental OPL fork with a unified PS2 and PS1 dashboard.

ID	Feature	What it does	Source
`E1`	Controller, memory card, storage and network status	A status strip showing each controller port, both memory card slots, the storage source and the network state.	src/evo_ui.c

xeRAbora

hacan359/xerabora — the PC client RiptOPL's RetroAchievements build talks to. Its console code lives on hacan359's OPL fork, branch ra.

ID	Feature	What it does	Source
`H1`	RetroAchievements pointer chains	Achievements that read game memory through a pointer can unlock. Without it, they never trigger — 22 of 50 in one measured achievement set.	commit 0c5f61a3

RETROLauncher

Spaghetticode-Boon-Tobias/RETROLauncher — a launcher written in Lua for the Enceladus environment, covering retro emulators alongside PS2 and PS1 games.

ID	Feature	What it does	Source
`R1`	Retro emulator ROM libraries	Libraries of retro ROMs launched through emulators such as RetroArch, SNESticle and TempGBA.	README

Modulo R1

AdityaKumar7209/Modulo-R1-Beta-Preview---PS2 — a Neutrino-based loader in beta. Only its PC server source is published.

ID	Feature	What it does	Source
`M1`	Choose between several network servers Optional	Lists every UDPFS server found on the network and lets you pick one. RiptOPL already finds a server automatically — see Network Boot.	README

Extended APA

L10N37/Open-PS2-Loader-Extended-APA — an OPL build for internal HDDs formatted with PS2 HDD Manager's banked APA layout.

ID	Feature	What it does	Source
`L1`	APA HDDs over 2 TiB Not planned	Splits a large internal HDD into APA “banks” and lists and launches games from every bank. RiptOPL stays on the standard APA layout — see Internal HDD.	EXTENDED_APA.md

Checked, nothing missing

Surveyed with the rest. Everything these offer is already in RiptOPL or does not apply to it.

Project	Why nothing is listed
ps2homebrew/Open-PS2-Loader	RiptOPL is built on its master branch. Its open pull requests are listed above under Upstream OPL pull requests.
ps2-mmce/Open-PS2-Loader	MMCE support, switching MMCEs to the boot card during in-game reset, and VMC groups are all in RiptOPL; the rest are upstream fixes.
Docmine17/Open-PS2-Loader-HTTP	RiptOPL's HTTP protocol comes from this project. Its only later change is an example `games.csv`.
NathanNeurotic/xerabora	A fork of hacan359's xeRAbora with no changes of its own; the upstream change is H1.
SvenGDK/Open-PS2-Loader	An OPL v1.0.0 build for PSX DESR consoles. Everything it lists is in upstream OPL 1.2, which RiptOPL is based on.
rodrigo1593-dev/oplfork	Two experiments with PADEMU module loading. The same author's Bluetooth change is U9.
PS2-Widescreen/OPL-Widescreen-Cheats	A widescreen cheat collection that works with RiptOPL's cheat engine as it is.
ps2homebrew/Open-PS2-Loader-lang	RiptOPL builds its UI languages from this repository, including Galician and Serbian.
ps2homebrew/HDLGameInstaller	A separate app that installs games into APA partitions. RiptOPL does not write APA partitions.

Notes

Already in RiptOPL, so not listed: the fix from wOPL PR #435 (remember the last played game when it is the first list entry), PS2RD cheat images (.img), cover art from ART/art.tar (Interface settings), cheats from CHT/cht.tar, the <name>_show_run theme key, RetroAchievements for physical discs, per-game OSD language, virtual memory card creation, and the older USB driver that upstream PR #1752 proposes pinning.
Shipped since the survey (PR #658): Ratchet & Clank 3 over SMB (was U5, from upstream PR #1761), Pro Evolution Soccer 2 defaulting to Accurate Reads (was U7, see Compatibility Modes), and Galician and Serbian UI languages (was U8, see Languages). IDs are not reused.
wOPL's config format: wOPL moved to libconfig. RiptOPL reads and writes both formats, so files the two loaders share, such as an app's title.cfg, keep working in both.
Device names: RiptOPL accepts usb0: and ata0: style names for its boot path and ties each launch to its device by driver name, but reads files through massN:. wOPL uses the typed names throughout. That is a different approach rather than a missing feature, so it is not counted.
CFG/cfg.tar: wOPL's README lists it, but neither wOPL nor RiptOPL reads per-game configs from an archive, so it is not counted either.
