Wanted: Source codes (for badass)
In order to improve my assembler it would be great to try it on existing projects.
So if you have sources for demos/intros/games that you don't mind sharing it would be kind if you could send them my way, and I'll try to get them working in bass.
They need to be buildable the normal way (Kickass, Acme or whatever) so I can compare the output binaries...
(this also means that if your type of demos requires special tools there is a greater chance I will include such functionality in bass).

Cool, it did a good job.
Try this, it uses quite complex macros with pass by reference labels: https://github.com/martinpiper/C64Public/blob/master/SpriteMult..
It should generate: https://github.com/martinpiper/C64Public/raw/master/SpriteMulti.. |

What does expressions on left hand side of assignments do;
SomeSybol+1 = something
? |

Not sure, but.. forcing 8bit (zeropage)? +2 = 16bit |

Forces zero page, before the exact value is known. |

I started converting this but there are so many Acme specific constructs I gave up after a while... |

REUTools 1.0 also contains source code... |

One thing i just came across again:
It would be nice to have the assembler emit an actual 16-bit operand with things like "lda $0000" and "sta $0000,x" as opposed to "lda $00" etc.
They seem to consistently insist on knowing better and "optimise" the code for zeropage access.
To counter this, all kinds of syntax (one fuglier than the next) to force specific address sizes were invented. Ugh. =) |

Tricky case. Do you have a suggestion for a good rule for this except in the trivial case with a constant?
I suppose a bit string concept like in 64tass might be sufficient. Not sure if 64tass uses it in that way though. |
