Hi guys,

Just chasing some heavily commented learner material in ASM, preferably a SCHMUP as I tend to view this as likely the easiest route to start with games wise.

Also, if you can be bothered - the closest thing to a datasheet for programming the SMS.. memory maps and so forth - I know it would be easy enough to find on my own but if you have recommended material would be awesome.

I assume controller inputs would be as easy as reading a 1 byte registers single bit states?

I recently made a new modchip for each revision of PS1, including one with a single wire BIOS patch in arduino C++, then ported it across to PIC ASM sucessfully, so I'd like to try moving onto some graphical stuff, and what better than the master system...!

There isn’t really a well commented entire game source published as far as I know. Maybe try https://github.com/maxim-zhao/ono - although this cheats on collision detection by using circle maths and I don’t think it’s well commented.

You might want to take a look at the source code for Fire Track; it's a SHUMP for Game Gear in assembly, with source code:
https://www.smspower.org/Homebrew/FireTrack-GG

I don't quite remember if it is heavily commented, but it is commented. The code for the movement of the enemy ships is pretty interesting.

Blockhead may be another option:

Thanks @maxim and @haroldoop

I'm just doing ONE more project then I will check these both out, as these old 8 bit systems are a passion having grown up on them.

project on hand is manually implementing a simple SPI algorithm without resorting to libraries and without having to loop any code to output a clock signal on a digital pin...

THEN
I'm all Master System!

But first, a break, where games are actually played and electronics and games are not tinkered with lol
