[WiP] Adding Cheat Support to more cores

General Development
#81

If it’s a crash upon actually loading the files, I can’t replicate it. Same with hitting the apply button with either cheat file loaded. Granted I don’t have copies of either of those games on me at the moment to test if the cheats apply properly, and I’m testing on a Linux 64-bit build from source. I can test those two games on Windows in a day or two.

You said that it crashes on load, but I need to confirm when exactly this happens. Is it right when you select the file? Is it when you hit the apply button? Or is it when you exit the menu to resume the game? Also, if you do not have “Pause when menu activated” enabled, can you enable it and try again?

If the crash happens when the cheat file is selected, confirm that the file name has no special characters. That shouldn’t cause any issues, but I want to rule it out.

What bothers me is that the only known way cheats can cause an emulator crash is if, on pressing apply and resuming gameplay, the cheat causes the game to crash so spectacularly that it takes the emulator with it. I cross-referenced the cheats in your post and confirmed that they are correct for what they’re named, so I doubt that is what’s happening.

The crash happens right when I select the cheat file. I never even get the chance to hit the apply button. “Pause when menu activated” is enabled on my end when it happened. There are no special characters in the file names. The file names for the two cheats I provided are “Final Fantasy VII.cht” and “Parasite Eve.cht”

Here are the steps to reproduce if they help:

  1. Load the “Beetle PSX HW” core (Though I tested it with other cores, and the same crash happens)

  2. Select “Cheats” under “Quick Menu”

  3. Select “Load Cheat File”

  4. Select and confirm the cheat file to be loaded

I really doubt it’s a problem with the games themselves, since this happens even when loading a cheat without a game playing in Retroarch itself.

Hi there

From what I’ve read so far, cheat support seems to be very much biased towards consoles. What about microcomputers? Many of them had devices which could insert POKEs into memory in order to cheat at games - for instance the Multiface devices for Sinclair/Amstrad computers (https://en.wikipedia.org/wiki/Multiface) - would this sort of thing fall under the cheat system, or am I barking up the wrong tree?

Cheers

Since virtually no cores had cheat support till you stepped in, it’s a safe bet that “whoever” is probably either you or no-one…

:grin:

EDIT: no issues with Beetle PSX HW here - just loaded Crash Bandicoot with cheats and all worked fine (build 815feba). Maybe an issue with your cheat files? Perhaps the encoding (mine are UTF-8).

#85

I updated Retroarch to the latest nightly build, and the cheats now load without any problems! Don’t know what was causing the issue, but it seems to be fixed now. Thanks for the help in looking into it, though.

Hoping Virtual Boy Cheats will also be implemented. I swear there was a VirtualBoy Emulator that was released that had this ability. It had Cheats and they worked. I think it was for the Wii. In case there will be, I have tried taking Cheats from rdragon and using them in RA VB Core, but it crashed on me. Here are all the Codes in the .cht File of rdragon:

@Offline am itching to have cheats in Beetle Saturn now. Would a bounty arouse your interest in implementing them?

My Wishlist would be PC Engine/Turbo Grafix, The Virtual Boy and Maybe Dreamcast.

#89

PC Engine/Turbo Grafix cheat support would be great. Is it worth starting a bounty to try help this happen?

I have put $5 in to a Bounty for cheat support to be added to Beetle PCE Fast:

Links:

#91

pce cheats? in what format? from what i gathered since there was no official cheat device for it, people have been using ips patches. forgot the link but that should be out there…

#92

Mednafen for PCE on windows has cheat support. Not sure if it is using IPS patches or another format.

#93

Thanks for the information does that include cheat support for PC engine CD games as well?I do use IPS Patches I have a guy that makes them for me. I’m just hoping for the future that if it’s supported on Windows not sure why you can’t do it on the Raspberry Pi core?

#94

@offline if you have the time, can you take a look at vba_next? cheats does not work.

#96

Suggest Cheats be added to FBA2012 Cores and ReDream

@Eignar17 - The problem is, the Cheats would not work. They would need to be correctly Adjusted +/- 1-3 Digits. I replied to your Post on the Github Page with my Link. I focused on the Games I have, but you should get the idea of it.

Also, you would have to remove the xFFxxxx from the Code and replace with x00xxxx . The Addresses are also limited, depending on the Game.

For my example, I will use SFA, FBA Cheat File (same thing applies to MAME, CPS2PSP Cheats as well)

cheat “Infinite Time” default 0 0 “Disabled” 1 “Enabled”, 0, 0xFFAE09, 0x63

cheat “Infinite Energy PL1” default 0 0 “Disabled” 1 “Infinite Energy PL1”, 0, 0xFF8441, 0x90 2 “Energy always set to 0 PL1”, 0, 0xFF8441, 0x00

cheat “Infinite Power PL1” default 0 0 “Disabled” 1 “Infinite Power PL1”, 0, 0xFF84BF, 0x90 2 “Drain All Power Now! PL1”, 0, 0xFF84BF, 0x00

Now, here was my results for RA Cheat Search (for the way it is built, I will shorten it)

Inf Time - 00AE08 - Same Values applied

1P Inf Health - 008440 - Same Values applied

1P Inf Super - 0084BE - Same Values applied

Speaking of Arcade, I was also able to get NAOMI Cheats made for a few Games. Good luck finding a few others.

view your interesant code gives an idea on which way to go

@Eignar17 and @Smoker1 I have been inspired by your recent posts to start a bounty to convert mame2003-plus cheats to RetroArch format:

#101

Yeah, ReDream seems to have much better Quality, and they also have the ability to work better with CDI Images.

Note - Not sure if ReDream has the Issue, but for some reason, in Hydro Thunder, you can not do a Hydro Jump. Think it has something to do with the Analog Triggers. Jump requires Accel ( R ) to be held while holding down the Boost (A), then quickly hitting the Brake (L), then back to Accel ( R ) while keeping Boost held.

As for the FBA2012 Cores, this would help greatly for N3DS Users, since Gateway Codes dont work anymore with Luma3DS CFW under the Rosalina Cheats (supposed to work with Gateway), or the Plugin Loader (Action Replay Plugin that works with GW Cheats better). But also, the Plugin Loader has Issues with ALL RetroArch Cores. 3DS System will crash when RA is Loading up. So if Users want to create Codes, it would have to be with the RA Cheat Search/Creation Feature.
