Very nice work indeed.
I'm still (very slowly) working on a disassembly of Space Invaders [PAL] for the 2600.

I started a formal German course this week; thirty hours a week for the next six months or so...

Just remember: Deutsche Sprache schwere Sprache :lol:
But it's always good to learn new things. I started learning Dutch last May — 20 to 30 minutes every day.

P.S.: If you need some help, feel ...

groepaz released his updated documentation No More Secrets V1.0 today: https://csdb.dk/release/?id=258111

Well, it was just announced that VCFB 2025 will be held online on November, 29th @ 15:00 aka 3:00 p.m. (UTC+1)

More Details: https://vcfb.de/2025/ (in German)

Cool. It would even fit in RAM on the Atari 2600. ^.^

Just found this fast 24 bit PRNG algorithm by Wim Couwenberg:

lda a ; Operation 7 (with carry clear).
asl
eor b
sta b
rol ; Operation 9.
eor c
sta c
eor a ; Operation 5.
sta a
lda b ; Operation 15.
ror
eor c
sta c
eor b ; Operation 6.
sta b

According to René Meyer they couldn't find a location, so there won't be a VCFB 2025.
The placeholder at https://www.berlin.de/events/5553055-22 ... tival.html also hasn't changed.

Thanks for the Information *thumb up*

If I recall correctly, older Turbo Pascal literature called 16 bytes Paragraph or Double Quadruple Word

Similar situation over at the VIC 20 Forum Denial.
It's currently closed for guests due to Bots eating away the bandwidth.

I know not 6502 and there's a disassembly out there, but Bill Gates released a scanned PDF of the Original Altair BASIC Source:

I already knew these two threads but thanks anyway
(And the code section on this site)
They might be helpful for others. *thumb up*

Well technically not just a 6502 only topic.
Since I wasn't around in the early days of computing in the '70s and don't know where (magazines or books) to start:
I'm searching for those vintage programming tricks like the BIT skip, which also appears e.g. in the source of Altair BASIC (8080: LXI ...

Which are taken (as stated here: https://codebase64.org/doku.php?id=base:io_programming) from the on-site Source Code Repository: http://6502.org/source/io/xmodem/xmodem.htm

But yes, Codebase64 is a fantastic source!
