Hey, where did you get the swamp tile? Are they wesleyFG's tiles? Can you tell me please. I want to use swamp tiles for my hack. Btw, I just finish playing the beta. I must say it is really a good hack.
But the fakemon of your hack are not that good. I think you should add some good offical looking pokemon. Anyways good luck.
ASM stands for Assembly.
The most powerful, and arguably the most difficult, hacking technique is editing the game's actual code, a process called ASM hacking ("ASM" means "assembly", referring to the type of programming language used for early console games). There is no set pattern for ASM hacking, as the code varies widely from game to game, but most skilled ASM hackers either use an emulator equipped with a built-in debugger or tracer, or run the ROM through a disassembler, then analyze the code and modify it using a hex editor or assembler according to their needs. While quite challenging compared to the relatively-simple methods listed above, anything is possible with ASM hacking (of course, within the limits of the hardware/software of the gaming platform), ranging from altering enemy AI to changing how graphics are generated. (Of course, the possibilities are still limited by the hacker's ability to comprehend and modify the existing code.)
If the developers used a typed language, the hacker may be able to compile their own code for the game in the same language if they have access to a proper compiler. One such example would be using C to hack Nintendo 64 games, since MIPS-GCC can compile code for the Nintendo 64.
