We need to create a pack with patched working roms!

Unsure on the legality of this, will gladly delete.
Not legal.

You are allowed to share profiles generated by the EXE. They only contain descriptions of the ROM file without actual data.
Luckily, I was able to download those illegal ROMs, so maybe the FBI will raid my house.

Soon after you released this tool, some smart merchants used your works to pack NES ROM and sell them as SNES multi-carts. Some of them crashed due to imperfect emulation. I wonder if the manufacturer of this kind of cartridge has contacted you? If we are using open source products to do business, I think it is necessary to display a blue screen error after the crash and display a "punishment" warning message such as "this cartridge is unauthorized, please refund it from the seller". :lol:
No seller contacted me directly but I heard about one known seller using my work. If anything, the blue screen shows the name of this emulator so people can research it.

Using the external bank address b0-b7 of SNES to emulate mappers. Using SPC to emulate APU. Very outstanding work
Do you mean banks $b0-$b7 for SRAM? I use $b0 for the game's expanded RAM while $b1 is for caching function entry points for the exe. I never access SRAM through mirrored banks so I can use more later if necessary.

Mapper emulation on the PRG side is done by changing the CPU's register DB whenever data accesses are made to $6000-$ffff.

Hey, the Atari VCS also had a 6502! Maybe, just maybe, could there be an Atari emulator akin to project nested? I know the TIA is weird and freaky and kernels control the scanlines directly without a frame buffer, but it has obviously been done on other hardware, so would it be possible?
