Game Corrections and Fixes

As I go thru my game folders getting them ready to be put on an SD card or added to Ultimem, I have found a few that have misspellings or errors in the code itself. I'll add them as I find and fix them. Feel free to add to this list. I've had some of these files for many years and collected them fro...

Fixing Star Defence

Does anyone know of a working version of this game? The copy I have and the one in Gamebase stores values at $a000 and $a001 and then falls into an endless loop at $1a2e. I'm sure this is some sort of copy protection but I can't seem to follow the code to see a work around. .C:1a1c FF FE FF ISB $FFF...

Further Expansion

With Ultimem coming out(got mine the other day. Woot!), I have been thinking about other ways the Vic could be expanded. Is there no way to map the character ROM? My thoughts led me to the idea of an internal expansion card at the character ROM slot itself. Something that held the char ROM and 4k of...

Re: New Release: Telengard (for the Vic-20 +24K)

3 blocks? Isn't each block 254 bytes long? That's 762 bytes more than you had. I did mention a lot of the work would have to be done by hand. I don't think a cruncher is going to combine data statements, drop the last quote on a print statement or change NEXT X,Y into NEXT:NEXT. I could be wrong on ...

Re: New Release: Telengard (for the Vic-20 +24K)

Is there a cruncher for the VIC-20? I have a cruncher for the C64 and have been pleased with it for many years. There is a cruncher for the Vic 20 published in Compute's Gazette called 'crunch' iirc. It had no bells and whistles though. There was also a 64 version that had options such as line leng...

Re: New Release: Telengard (for the Vic-20 +24K)

Not really sure why you would want to compile it. You would most likely end up with a file larger than it is now. I think a cruncher might be a better option. A cruncher could optimize the BASIC code for the 88 character line length of the VIC-20 instead of the 80 character limit of the 64. A renumb...

Re: Making a random number in Assembly

I've often thought about having a person type something in such as their name or what not, then using what they typed along with a time resulting from how long it took them to type it in to generate the seed. Obviously this wouldn't be practical in every instance, but at the start of a game or somet...

Re: a new Game for the VIC-20 Fort Apocalypse

I've checked out the code of this little gem. The custom characters are embedded in the .PRG file and it seems to only use 3 commands from the super expander; RJOY(),COLOR, & SOUND. Someone with a little smarts could easily convert it to be used on a regular VIC.

Re: Two unknown cartridges

I extracted the code with a hex editor and then ran it thru a disassembler at: http://www.e-tradition.net/bytes/6502/disassembler.html This is what I got from it. The code from the bin file should be mapped at $6000. This is the first few lines: * = 6000 6000 4C 0C 60 JMP $600C 6003 4C 3F 60 JMP $60...

Re: Games we want to see

I ran across a puzzle game on the internet that seems like it would be an easy conversion to the Vic 20 called Ninja Twins.

Re: Atari Dump found by Archaeologists

Archaeologists. Right. The future when archaeologists are unearthing 1 million year old computer and hardware dumps. Classic stuff. At least this puts away that myth about the dump sites. :D
