Good idea have the alternate rows of aliens moving in opposite directions.
But I don't know what you mean about the VIC1001, apparently it's 3583 bytes free too.
(TBH I had never tried VIC1001 settings on VICE until today)

Re: "Ultimate Expansion" - new firmware for FE3
i have the FE3 as an .prg file from the BADAPPLE demo with rev020. to play on VICE emulator, first add fe3badas7.5.prg as a Final Expansion cartridge. Then attach badrom7.5.d64 as a 1541 disk image. If the Bad Apple demo indeed also worked with the original Rev. 020, then just by pure luck (most pr...

Re: VIC listing program
There seems to be more functionalities in the repository tools other than just list programs to pdf. For the record VICE can print listings to bmp if you configure the printer, and can copy and paste text to and from the editor (as long as there are no control characters). But your approach looks mo...

Re: Vic1001 game list
Some issues of this magazine are on archive.org. They look pretty good. I have extracted the listing of Zena. I'd like to know what program they used to enter the hex data.

Re: Trained VIC20 Games , Cheatcodes and Trainer Pokes
I played the trainer and after7 or 8 levels it kicked me out to BASIC with a READY prompt, without rebooting. Today I watched a gameplay on YT and the game has several more levels. I wonder what happened.

Re: Is this a particularly low serial number and if so, should I be excited?
I own 3 VIC20s with serial numbers around 10k, PAL, PET style keyboard, in none of them the case serial number matches the board serial number. I don't know if they have been repared or something, they come from eBay, but I 'm suspicious if it's like that for all VICs.

Re: Keyboard Buffer and Ctrl/Shift/CBM etc
I guess your emulator should take care of the via registers (the keyboard matrix) and let the kernal interrupt do the updates of these registers you are talking about. I guess otherwise you are rewriting the rom or designing your own system. In this case, I guess you should compute the correct ascii...

Re: Double buffering screen bitmap
This snippet iterates reg.Y from $4 to $FF and fills $200 to $2FB with a pattern (which I don't know). Anyway, double buffering would be to write to $1000-$17FF while $1800-$1FFF is on display, and then swap the roles. I doubt you can double buffer pictures larger than 2kB on a regular VIC20 (withou...

Vic20 and music keyboards. Are you the 8 bit guy undercover. Anyway, it would be a good topic for one of his videos.

Re: MINIGRAFIK lineart
It's not clear what you mean. Once R/150 is converted to an integer, the rest of the statement just takes bit 0 and branches if set. You don't need to call the ROM, it's straightforward assembler: lda result_lowbyte and #1 bne @label60 or lsr result_lowbyte bcs @label60 I don't see the need to speed...

I have some trouble to send the programs as a file, i dont know why? I think you have to zip prg files And sorry again to send a lot of code here. I find code as text is a comfortable way to share code if there are no PETSCII or control symbols. In this case it's possible to copy and paste it into ...

Re: Cartridges!!!
My original VIC is still alive. But back then at some point it had started to freeze whenever the fitted cartridge had a slight movement. Most times I had the 16kB cartridge installed. I was afraid some day the VIC would break, so I started to hate swapping cartridges. Anyways I only had Sargon II, ...
