Convert native cheat codes to the RetroArch format

[eadmaster]

There a lot of cores currently that only support cheats in the RetroArch format, while this repo only provides codes in Native format (e.g. GameShark):

• https://docs.libretro.com/library/mupen64plus/#features
• https://docs.libretro.com/library/pcsx_rearmed/#features
• https://docs.libretro.com/library/flycast/#features
• https://docs.libretro.com/library/yabause/#features

This creates confusion among users, who assume cheat support is missing in these cores, while it is not the case actually: libretro/beetle-pce-fast-libretro#93 libretro/beetle-saturn-libretro#5

So i've made this quick and dirty script to convert the cheat tables format:
https://github.com/eadmaster/dotfiles/blob/main/bin/chtnative2retroarch.py

It's still missing support for encrypted/conditional/increment/activator codes, but i've found it's already working well in most cases.

Possibly it can be merged into the scraper script, to have the cheat tables converted automatically after download.

Sir it's just a simple python script file. Most of us don't know how to use it. It would have been better if you had made a guide or tutorial instead of leaving it to us how to figure it out.

example usage:

python chtnative2retroarch.py "18 Wheeler (Japanese).cht" "18 Wheeler (Japanese) (converted).cht" dc

Nice work, @eadmaster. Do you think it would be worth having the duplicate scripts hosted in this repository? Suffixed by "(RetroArch)" or something?

Sorry butI'm getting this error, and do original file have to be in .cht format as gamehacking has no download option for download sadly. I've attached snaps for both error and original cheat file

@chelnov5 : Download the script in raw mode, you saved the html page.

@RobLoach : it would make sense for the supported systems: sat, n64, dc, ps1, pce(cd)

Thanks now it worked. Now I'll check the codes in game.

I'm trying to get the symphony of the night saturn cheat codes to work, but I'm not having any luck. I changed this file extension from "cht" to "txt" so I could upload it here. When I run the python script, it says all of the formats of the cheat codes are unsupported.

It would be awesome if you could look into this, as this is a very popular game.

It doesn't work on the Beetle Saturn emulator even though this is the cht file in Retroarch.

Saturn/Castlevania - Symphony of the Night (GameShark).cht at master

[eadmaster]

replace all "+" plus signs with spaces in this file , then:

$ chtnative2retroarch.py Castlevania\ -\ Symphony\ of\ the\ Night\ \(GameShark\).cht Castlevania\ -\ Symphony\ of\ the\ Night\ \(GameShark\)2.cht ss

output:
Castlevania - Symphony of the Night (GameShark)2.cht.zip

If you download a cht table from here there is no need to replace the plus signs.

Would it be possible to get it to convert cheats for the Sega CD too? Primarily trying to get ones that use Word RAM and PRG RAM working with RetroArch (Genesis Plus GX). As-is they currently don't work with the core, so trying to convert to RA native cheats.

This is a example: https://gamehacking.org/game/85288
