(Request) Megaman & Bass GBA

[asscock]

Jump in midair, Invincibility codes in code breaker format? Either would be great! Thanks!

[bungholio]

I tried, and I hate the tools out there for GBA. Everything's buggy, broken, crashes a lot, and nothing has breakpoints on read/write.
I don't know what version yours it, but mine is 0902 - Megaman & Bass (U), CRC32 = EEA68C2E

If I could find something that lets me set breakpoints on things I could change that walk in air code to instead trick the game into always thinking you're on the ground when you press jump so you'd be able to jump in the air as needed. The value to fall to the ground is 00 instead of 02. I'm not familiar with cheat device formats. I also tried finding buttons held down since you even said codebreaker because I used to make many button codes on the old PS2 codebreaker, and that would also fix the walk in air code, but I'm tired of fighting with all of these emulators and the crashes and other BS.

Use no$gba for GBA and NDS games, it has built in debugger:

I saw it and tried it but have no idea how to set those breakpoints. I don't see cheat finding tools for scanning in there anywhere either. I see I can set a break on a line of code, but when I tried setting a break on my memory addresses nothing happened. I'm very unfamiliar with how to use it. I can see a lot of stuff I use in it but if I can't figure out how to set a break on read or write then I can't even start with any of it.

When you want to set a breakpoint in NO$GBA, find the RAW address of the cheat you hacked in VBA or another emulator.
Then, click on the "Debug" tab and click on "Define Break/Condition."

Now, let's use an example.
Let's say that the code we want to hack, is the "Jump In-Midair" code that, asscock wanted.
The address that you listed was: "03004F7C."

Now, click on that little bar that pops up after you click on Define Break/Condition.
Type this into the little bar thing: [03004F7C]!
This is a "write" breakpoint. If you want to use a read breakpoint, then replace the "!" with "?"
Then do whatever it is you would normally do to make the game break.

That's new and interesting to me, never knew ! and ? would be involved with read and write breakpoints. If I ever hop on a GBA game again I'll try it. Thank you sir.

I took another try at the jumping code, but it's still not quite right. Somebody that knows how to use that debugger better should be able to fix it.

It's better than above and kind of controllable, you'll see from trying it. It still needs to be fixed.

[Dybbles]

I tried it and it indeed needs to be fixed.
I'll take a look at it. I could probably use Bass's Double Jump routine to see if I can manipulate MegaMan to jump in mid-air.

A little buggy, but try this for now.

Multi-Jump ("Jump In Midair")

I may or may not fix this. ( ͡° ͜ʖ ͡°)

Edit: Some AR v3/4 ASM codes.

I have noticed about the "All CDs" code from here:
http://gamehacking.org/game/5283

The code in Codebreaker/Gameshark SP/Xploder format

82027DA0 FFFFFFFF
82027DA4 FFFFFFFF
82027DA8 FFFFFFFF

It is incorrect.

Here's the decrypted All CDs code in pure Codebreaker format that I came up with:

82027DA0 FFFE
82027DA2 FFFF
82027DA4 FFFF
82027DA6 FFFF
82027DA8 FFFF
82027DAA FFFF
32027DAC 001F

tested in both latest versions of no&gba (2.8e) and VBA-M (2.0.0 beta 2).
