Figure out what the text works like and you should then be able to eliminate vast swathes of the change list.Beyond that then yeah time to play with the affected mechanics; don't know what it is but if it affects scores, experience, pickups or similar then you have the start of a tracing session there.

Quote from: Psyklax on June 05, 2019, 01:10:55 AMThat narrows it down, but it still baffles me why people ask for help while keeping the game and system they're interested in a closely-guarded secret. If you're dealing with the NES or SNES then a bit of assembly knowledge would help because you could do a trace log and look at what's going on with the registers for controller input. If you don't know about that stuff then it might be harder to figure out.

Quote from: Psyklax on June 05, 2019, 12:05:33 PMSo after playing the game and having a look, I can see one thing that you mentioned: the bit that checks if you're at the right height to do your spinning kick. At $1827D in the ROM, there's an instruction which branches if your current height is equal to the one given in the ROM at $1828E, which is 02. If it is, you do a spinning kick, if not, you don't. Remember I said about doing a file compare? Open both the original ROM and the hacked one in HxD and press Ctrl+K to open the file compare menu. This lets you see every single byte that is different between the files, and I would imagine something around $1827D is different. Worth checking it out.As for the rest, I haven't really looked, but it's a start.
