Re: ASM502 - a new 6502 assembler.. (WIP)
Yeah good luck What makes cc65 strong is the library and its ecosystem anyway, and if you rely on the optimizer of a 8bit compiler, you are doing it wrong

Re: ASM502 - a new 6502 assembler.. (WIP)
cc65 cant really do more than it does now (peephole optimizations) - it has to be rewritten to use an IR first - acqn has been working on it iirc, check his repos

Re: ASM502 - a new 6502 assembler.. (WIP)
In general, with user-written code, an assembler will not have a good idea about these conditions. It amounts to execute arbitrary code already in the assembler which, IMO, is not its job. Peephole optimization is well possible in an assembler. Actually Daniel Dallmann (Lunix) wrote such optimizer ...

Re: Switchless NTSC<->PAL
Couldn't you make it generate the reset signal as well (would require a patch cable of ofcourse)?

Re: ASM502 - a new 6502 assembler.. (WIP)
I would love if someone made a small assembler like ASM502 for the ARM, targeting the pi, android, Arduino, blue pill etc, so you didn't have to run an SDK full of bugs taking a gigabyte or more.. Just build GAS for ARM? For all those modern CPUs it really doesn't make a lot of sense to make a cust...

Re: Using Exomizer
I'd rather use some simple RLE packer for the first block though (and perhaps tscrunch for the final step)

Re: Assembler
I forgot the most valuable advice for this kind of question: use whatever the people you can ask use. It doesn't really really matter if you use dasm or 64tass or acme or any other of the popular ones (their feature set is very similar) - but it helps a lot if you can throw some quick questions at s...

Re: Assembler
I recommend ACME as a simple straightforward assembler. While CA65 is really great, its mostly aimed at experienced users and huge projects. ACME or 64tass are more like traditional assemblers, and probably easier to get started with.
Re: ELITE
I'd just do what pretty much became the standard in recent days for (larger) C64 games too: use a cartridge. That eliminates all concerns with memory.
Re: ELITE
The bitmap shouldnt be a problem - you can do that with a charset matrix.
With fully expanded VIC20, porting Elite sounds quite doable to me - still a lot of work, obviously

Re: How to convert Tap files to D64?
Use TapEX -> https://csdb.dk/release/?id=237663
load the tap, select "extract prg" from the menu, and it creates a directory with all files. For vic20 tapes you will probably have a pretty good success rate

Re: Corrupt end of basic program
Yes. However, if there is a reliable way to reproduce this, i'd still like to knowIt is very unlikely that you found a bug in VICE here.

Can you do actual scans? The Tape Archive aims for highest quality - i don't think they will accept photos like this
