I just want free access to all the program memory (including the tape buffer), but I also want to check the directory at times when I cannot remember the last draft name. Now that I write this it occurs to me that I may just need a small routine that pulls that last saved filename (if that's easier...

I got a note on my wall saying:
C = 0 : reg < OP
C = 1 : reg >= OP
because I always forget which is which (must be due to my age...)

I definitely need that on a mug!

All features are now implemented and I am proud to announce the official release of the RAM disk: 1.0.0 So what do you get? You can load and save files from and to the RAM-Disk slightly faster than using SJLOAD and SD2IEC. Since that also comes with the FE3 and of course all data in RAM is lost if y...

Before working on the SID converter I had to walk the dog, then after adding the option to select the song for analysis & conversion I took a look at the SID emulator and noticed that there are already 32 ZP locations free to use. Then I tried to convert Parallax again, but it still did not work...

Most SIDs won't convert because of failing INIT oder too many ZP-addresses. We had a discussion about freeing more ZP locations in this thread, but haven't had the time yet to put it into the player routine. Source code is included though ;) I made a pack of 6 conversions for download here Great, t...

Unfortunately, most SIDs won't work with emulation on the Vic-20 or they sound just awful. Anyway, I put together a release of the converter for download here.

Please share any working SIDs you find! :D

Update: new link with reduced download size.

You could also use the load address of a program (first two bytes) to detect the proper memory configuration as follows: $1001 = unexpanded $0401 = 3K $1201 = 8K+ $10F1 = 8K+ (Minipaint picture) This method does not work for multi-part cartridge image. But these sometimes have file extensions that i...

Which brings me on a similar thing: in a while, I'm gonna get a VIC20 again, after 24 years! For free even! Nice, grats! But it comes without a power supply. Do you guys have any suggestions for how to get one? Either an original one or something modern that fits the needs and limits of the VIC? I ...

You are right, it could be done. 3 well saved bytes. :)
