CT6 CST1 "Insert ASM" C2xxxxxx Gecko Code handling is incomplete
0%
Description
What's the problem?
When several codes that allow Brawl- to function properly, the game and emulator crash. The following crash the game:
Tech Window v.05
Shield Stun V8
Dash Dancing
Universal Walljumping
Included in the extra information will be each code's hex.
Dolphin version with the problem (as it appears in the title bar, Ex.: "R
4779" or "R 6403M"):
The version used is r7528.
(optional) Dolphin version that does not have the problem:
Operating system and version: Windows 7 Ultimate
32-bit or 64-bit: 64-bit
Game ID (as it appears in game properties, Ex.: "GZ2P01" or "RSBE01"): RSBE01
Build command-line (not on Windows):
Was the ISO a plain dump from disc, compressed and/or scrubbed?
The ISO was originally a plain dump from the disc, modified so that it has all of the files Brawl- uses (over 300). The ISO itself is not a problem, as it does not crash unless codes are used with it.
Please provide any additional information below.
The codes and their hex, in order of mention above (any extra text after the code is OMITTED in the actual code used, codes are entered in proper Dolphin format):

When USING*
Wow, that one is a real slip-up. Sorry, guys.

Those are all "insert asm" type codes.
Updated by Klinechr123 almost 13 years ago
I'm not exactly sure what that means. Can you elaborate? I'm a bit new at this.

Using cheat codes which modify memory (Gameshark, Action Replay, Gecko, etc.) Can cause instability in any game at any time. If these codes are correct and don't cause instability on real hardware then it's either an issue with emulation accuracy or it depends on the software running at 100% speed for some reason.
If there is an error in the codes, please post an issue in the dolphin-cheats-database SVN instead where it can be dealt with quickly. Generally speaking, though, instability can and should be expected when using cheat codes like these.

Thanks for the timely response and great explanation. I'll be sure to take my issue there posthaste.

Sorry for late response. I think this issue is due to my "insert asm" type (CST1) handler. I implemented the CST1 handler in Source/Core/Core/Src/PowerPC/PPCAnalyst.cpp by interrupting the PowerPC code analysis routine. My code works as inserting PowerPC code into where the code specify. This behavior is different from what the real Gecko does. In ordinal cases, my handler works well. But if the CST1 code creates subroutines, it does not works because my handler can't handle such code. If CST1 code create subroutines in itself, my code does not work and the emulator will crash. Currently I don't have any ideas to fix this issue. Unfortunately I don't have time to commit for Dolphin project now. I'm sorry.
