# The Manic Miner Machine
The Manic Minder Machine is a very, very small Apple II emulator that I built specifically to run, on a modern computer, the unmodified 6502 version of Manic Miner that I made for the Apple II. After I finished the harte_6502 project, a 6502 cycle-accurate CPU emulator, I thought about doing a Commodore 64 emulator, but then realized that Manic Miner loads into RAM all in one go (well, the loader loads it), and I don't use any ROM routines.

Manic Miner uses only the Keyboard ($C000), Keyboard Strobe ($c010), the speaker ($C030) and 2 hires banks (with toggles at $C054 and $C055). So building an emulator should be very easy. Well, it was.

My speaker code is beyond terrible, but I'll maybe figure that out later. Turn audio off with M or S (Music & Sound). ESC will quit. O & P for left and right and SPACE to jump.

# The Speed
On my M3 Mac Mini, the harte_6502 test run in 11s and on my windows PC in 35s. But the emulator runs great on Windows, and can run a little faster than the 1.023 MHz that the Apple II runs at. But the emulator runs pretty slow on my M3 Mac Mini. I did not look to see if the issue is related to SDL_GetPerformanceFrequency or something else.
The game runs equally well on my M3 Mac Mini as well as on my Windows PC. I did not build for Linux.
# The Future
I will probably not do too much with this. I'll see about fixing the audio.
