My guess is because of the recent Libretro hack, no assets are currently available for download - including cheats.

@mitu /opt/retropie/configs/mame-libretro/retroarch.cfg is already in that state (and it's identical to retroarch.cfg.rp-dist)

@grant2258 I started a new topic on this to not clutter this one.

Reinstall and update game still crashes.

@mitu edit: duh got it. Thanks again.

@Clyde I'll try to figure that out (I'm new to retropie). thanks.

I've seen that there's a Python front-end for Mupen64 that has a GUI where you can select different cheats, but I'm guessing it just loads them before starting the emulator the same as the CLI you posted.

How did you even get yours to run?
For the life of me, I can't get any PCE cd games to run.

Okay so I got the following cheats for Final Fantasy 8 entered and uploaded into the files but when I activate them in the game menu the only one that actually works properly is the 255 AP and the Infinite Item Usage. All Items and All Cards doesn't work properly (All items gives me 100 potions and All Cards give me 127 of one card) I've checked multiple times and they are entered correctly, can someone please give me some insight as to why they aren't working? I threw the Master Code in there after the fact but it didn't change anything at all.

nothing needs setup the default retropie config is set to

system_directory = "~/RetroPie/BIOS" your problems are arising from messing with the default config , you need to be careful when changing the configs on retropie.

retropies default mame install copies the the cheat dat from here https://github.com/libretro/mame2003-libretro/tree/master/metadata to the bios folder on install. your not supposed to save retroarch configs with retropie unless you know what you are doing fully. The cheats do work on a default install nothing needs done.

Okay, finally after hours of tinkering under the hood I'm finally able to make Shining in the Darkness work with cheats without crashing RetroArch.

I tried changing the core emulator from pico to a different one and that didn't fix it. I tried renaming *.cht files and copying templates directly and that didn't fix it. I tried a different version of the rom with all three Genesis/Megadrive cores and that didn't fix it.

I couldn't seem to figure out how to use my USB keyboard to input cheat codes manually so I painstakingly physically drew by hand a character map using my controller and a pencil.

Eventually, I managed to figure out exactly where all the necessary keystrokes I needed were located and input a couple of codes and they WORKED! I was able to save this data as its own file using RetroArch and (crossing fingers) reloaded the game from scratch and successfully reloaded the newly made cheat file and it indeed works just fine.

I then input all the rest of the codes and the older ones and created a new file to load with the game.

Whew! That was an adventure.

I'm currently new to making posts on these and am wondering about if someone has found a solution yet as of March 25th, 2019. Thank you all in advance!!

It looks like a few people have found my script. I'm glad to see it used. Hope everything goes well for you all.

@mediamogul Thanks, this was helpful in getting advmame cheats working for me but I'm noticing that every time I close and re-open a game I have to go back in and turn the cheat back on. Is there a way to make it permanent?

Is there maybe a setting in the retroarch.cfg that needs added or turned off?

@mat said in lr-picodrive Cheats Broke?:

I am always leery of trying something outside of the default

What's important is what works best for you. The defaults are intended to cover a wide range of use cases, but quite often the alternatives can potentially work better for specific goals. One of RetroPie's biggest strengths is that it allows you to tailor your emulation experience to how you see fit.

@mediamogul Oh great thanks for updating that. Maybe it would be worth noting though. I'm not sure of the other versions of RetroPie but the one I'm running, 4.3.8 I needed to turn on the Online Updated Like mentioned above.

Thank you so much. I have a friend I'm setting up a disk image for and he really wanted to have the cheats work.

@DarioRomero said in Hoto: use Gameshark cheats for the PSX:

I followed the instructions closely but when I bring up the emulator menu theres no directory called Extra Stuff. What am I missing or how can I fix this?

Are you sure you are using pcsx-rearmed and not lr-pcsx-rearmed? That last one is the default if I'm not mistaken. In pcsx-rearmed the menu opens when I press Escape on a keyboard. If it doesn't then you might be using the LibRetro version of PCSX (i.e. the mentioned lr-pcsx-rearmed). Confusing, isn't it?

Good luck! :)
