Isn't the binary in the PRG folder working?

One typo is in 270, the POKE at the end is supposed to be for 7698. That fixes the ; and shows a start countdown. Looking for the other char.. Edit: Holy shit! The author is using the character data overlapping with the screen RAM. The content of the playfield is used as source for the starting ligh...

Found a few typos in line 250, and 360. That fixed the gameplay, but the broken chars are still there. I noticed that the custom chars seem to be placed very close to the code/screen RAM. Stopping the program and typing on the screen modifies the start light chars already. Edit: How can .prg be an i...

In line 750 you need to have a Cbm-J after the red color (instead of the space). The code checks for this character.
Once you do that the player ship can be hit.

From what I can see that does the trick.

The problem seems to be that the values returned from PEEK(37137) have the lowest bit set, so they result in 370 and 366 for Q, instead of the expected 369 and 365. I do not know enough about the VIC20 when this bit gets set. It seems to be set even when starting the game in VICE. With VICE a clear ...

New version 8.0 of C64Studio is up! This has support for VIC20 8x16 char mode (in charset, char screen and map editors), plus in the graphic screen the option to export as charset is available as well. Thanks to Mike there's also a Minipaint import available. Binaries and source code available on Gi...

C64Studio also uses VICEs binary monitor command, and lets you step throw your own code, breakpoints, memory views, etc.

The code is open source, so you can take a look at how it's handled:

Whoa, that was fast. Here's the update. Thanks!

I have partially, it's from the Forum64 cloud. It has a small gap plus a few lines are missing in that scan. https://www.georg-rottensteiner.de/webmisc/Computerposter 4 Poster.jpg https://www.georg-rottensteiner.de/webmisc/Computerposter 4 Listing.jpg https://www.georg-rottensteiner.de/webmisc/Compu...

Thanks for the link, will do this.

I'd just like to make sure all the kinks are ironed out. The poster listings were notoriously bugged. I'm surprised it's working as good as it does.

Hello people! Since I just registered I also want to announce my Retro Dev IDE C64Studio, which beside the most prominently supported machine also has support for VIC20. Hope that's not interpreted as spamming. The in built assembler defaults to ACME syntax, but can also work with DASM, TASM, PDS di...

Hey thar! I've got this forum recommended by CBMWarrior from Forum64. I never had much contact with a VIC20 back then, only a friend had it. So my knowledge is very restricted and mostly of the C64. I'm a developer by passion, and beside a lot of Retro Remakes for PC I also wrote a Retro IDE (C64Stu...

Hello thar! A user from Forum64 (CBMWarrior) suggested typing in the Computer Poster game "Schatz des Drachen von Mordor", which I did as best as I could. A few spots weren't properly legible and had to be pieced together from the C64 version. So far it mostly seems to work as intended, bu...
