Default Mystical Ninja: Starring Goemon levitation issue

I'm a fan of the good ole "Press L to levitate" for games that I've beaten but I notice that this cheat wont work after the first giant robot battle (Impact). Has anyone else experienced this and are there any workarounds?

Probably self modifying code. You will need to examine the cheat code and use some ASM hacking to modify the function.

Another thing you could do is look for the memory value after that part of the game to locate the new location in memory.

I'm impressed by your expectations of these posters. Even I'm not that cruel.

They could just switch the core style to "Interpreter" if the whole cause was protect memory.

interesting, would that work?

I think that the post might lead them to trying to resolve it, but who knows.

If I had the code and a save I might make a quick attempt at the GS code. ASM is still too time consuming for my current skill set.

If your theory was accurate, then yes, it's guaranteed by definition to work.

That is, if you're correct about self-modifying code being the cause. Self-modifying code invalidates the instruction cache on the x86 server's side when any recompiler is used. An interpreter does not have an x86 server but only the MIPS client and does not have to synchronize anything if code space were overwritten, so the problem of self-modifying code becomes irrelevant which means an interpreter core should invalidate any issues caused by cheat codes being corrupted by self-modifying code.

lets see if the code and save states get posted. I would like to look into it, as its defiantly interesting topic. However, I do jump to "theory crafting" quickly when talking with first time posters..
