Direct SAM port to modern systems!


Recommended Posts

I was amazed to see that it's possible to directly run SAM (Software Automatic Mouth) on linux at least *without* emulation!

 

The technique used was to port 6502 assembly line by line to the literal C equivalent see

 

https://github.com/vidarh/SAM

 

eg.

lda 56 => A = mem[56];
jmp 38018 => goto pos38018;
inc 38 => mem[38]++;

 

This is described as "semi-automatic" and is probably unreadable!

 

There is a another version at

 

https://github.com/exploser/sam

 

where the C was ported again semi-automatically to Go (a simpler, more modern C like language and my current favourite!)

 

This is the version I tried and it can be installed with go as "go get https://github.com/exploser/sam"(although I had to add a asla header file package).

 

It sounds exactly as I remember!

Modern computers are fast enough now to do emulation in high-level languages.

There's numerous Java based emulators around, fairly sure even the C64 is covered.

 

Just getting rid of the DMA jitters from Atari SAM (even screen-off since refresh cycles still happen) would vastly improve it's quality.

True but this isn't conventional emulation.

 

It's actually producing a native program which runs directly on linux, windows and mac without the use of an emulator directly from 6502 assembly language.

 

Clearly the IO routines (sound in this case) use modern native APIs directly but the bulk of the logic of the program is equivalent to the original.
