[PS1 devices] Use your [special device : light gun…] with POPS

[Original tutorial by AKuHAK] @ASSEMblergames

1. Find a PS2 game that supports your special device and look inside its content;

2. Look for some IRX files;

3. First file that you need is SIO2MAN.IRX. You need this module for making other modules working;

4. Copy it into POPS folder and rename as MODULE_0.IRX;

5. Then search for your specific IRX files. It can be one file or multiple files. For light gun, it might be USBD.IRX and USBGUN.IRX;

6. Rename them as MODULE_1.IRX, MODULE_2.IRX, ... etc. You have to experiment to find the correct order. For light gun, first .IRX might be USBD.IRX and second .IRX USBD.IRX;

7. Copy these files into POPS folder and run your game. If you got special device to work – have fun!

8. If you have no luck – you can copy specific IOPRPxxx.IMG from your game into POPS folder and rename it as IOPRP252.IMG. In such way, you have to delete POPS.PAK and use only POPS.ELF + IOPRP252.IMG.

9. If it still doesnt work, you can also try to add more modules from your game (repeat 6th step) or you can try to change modules order.

Notes :

Don’t forget that USB devices may not work if you use POPS in USB mode.
These manipulations doesn’t mean that you will be able to use all special functions. It only means that your device will be recognized properly (so all standard functions will work).
