Commander X16

I've put the source code up on github if anyone's interested: https://github.com/bcampbell/scumbotron
Requires llvm-mos-sdk and golang to build.

Offload the graphics and maybe some of the code to a separate file. Put less used routines in banked ram TL;DR: I'm too lazy. Separate files are cheating! :-) I decided pretty early on that getting it into a nice single .prg file would be a nicely arbitrary restriction. My self-decompressing .prg f...

Oh! I missed that - it looks fantastic!

Yeah, I'm already up against the 40KB code limit :-( The .prg contains compressed code and graphics data. Upon startup, there's a little bootstrap routine which decompresses the graphics out to vera ram, then decompresses the code out to its full 40KB(ish) glory, overwriting the original .prg. So it...

Very nice implementation of a Robotron-a-like. Maybe add the control system on Jeff Minters' own version, which I always liked, and means you don't have the twin controllers issue. Llamatron was fantastic! You're talking about the hold-down-fire-button-to-lock-the-firing-direction single stick sche...

New 4th version!
Only minor changes:

- Rifasharks now worth 100 points (rather than 10)
- Rescuing Heavily Armoured Space Marines now refreshes your powerup time, so it's worth saving the poor fools.
And I _still_ can't get past level 40, dammit.

I just managed to get to level 41 (out of 42).
There are a lot of rude words on my high score table.

So it's on a word boundary and who knows what might be needed in the future. Is there something significant about 32 that makes it a better boundary than 16? The palette can be directly loaded to $1FA00 in VERA Ram. Oh, yeah, I'd forgotten that palette was hardwired at $1FA000... so if you load the...

Proposed Gen-4 CX16:

JAMMA-edition CX16. Plonk one into your JAMMA cabinet for all that CX16 arcade-y goodness!
Even if it's just a JAMMA adaptor for the Gen-2 or 3 hardware, that'd be rather cool.

(I'm about 30% joking - the more I think about it, the more it's something I want to see!).

My initial thoughts: 1. Why not make the version (byte 3) ASCII? It's not like you're going to need 256 versions. And being able to eyeball the file and see "BMX1" (or "BMX2" etc...) would be nice. 2. Why the 19 byte header padding? Why not make your header 16 bytes instead of 32...
