[BUG]: Cheats disabled when launching another ELF

[YukiXXL]

Describe the Bug

Cheats get disabled when running another ELF.
I have Champions: Return to Arms Demo disc which has two ELFs. SLUS_291.26 runs first and CORE.ELF inside BG folder second.
In milisecond I can see that cheats loaded and then it shows that it couldn't find any compatibility or other patches/cheats message.

Reproduction Steps

• Get any Demo disc game
• Enable cheats for the game on the demo disc
• Run the game

Expected Behavior

Cheats working.

can i have an example of the cheat file used?

[refractionpcsx2]

are you launching the game from the ELF? you might need to change the CRC in the filename to the new CRC, but the main one it uses when it boots the disc should be fine.

I am launching the game normally. I checked the CRC from 1.6 and it uses the same one.

It didn't allow me to post .pnach file so I renamed it to .txt.

it looks like you may have to update the cheat to thew new format https://forums.pcsx2.net/Thread-Sticky-Important-Patching-Notes-1-7-4546-Pnach-2-0

I make codes on 1.6 since 1.7 is unstable and tends to crash more than 1.6 when testing.

Found the CRC. It's C723B6C6 but now the problem is that selecting cheats isn't possible.

[Mrlinkwii]

you need to update to the new format , to be able to select cheats

you need serial_crc.pnatch i think

It doesn't work as it needs it's CRC from an ELF that gets launched first. Otherwise, cheats cannot be selected.

[YukiXXL]

Best thing right now is to stick with the old pnach system and enable/disable by commenting them out in the .pnach file and enabling cheats in the emulation settings.

I would say it's better to accomodate to work better than to bypass the issue.

PCSX2 is improving per revision, if people want to go back to older versions then we aren't doing something correct (yet)

[YukiXXL]

I also keep in mind to make the cheats work on real PS2 Hardware aswell. So far they work on mine fine with ps2rd. I don't know if cheats get loaded the old way (1.6) or the new on PS2 but I aim for compatibility.

[refractionpcsx2]

one thing you can do, once it swaps elf, you can go in to the per-game properties and it should show the cheats for the currently loaded ELF, iirc.

It'll show the primary/disc elf.

1.6 is dead, move on, 2.0 release won't be that far away. I see the point about it being an edge case with a loader ELF - in this case, I'd suggest duplicating the pnach file for both CRCs, but leaving the codes empty for the loader.

We will not be restoring the old behaviour. It was broken from the beginning, and caused crashes/broken games when patches were applying to the wrong ELF.
