... everygame on a huge rom chip ... So it will be a thing between MegaCart and FE3? A MegaCart with SD support, - a FE3 with huge ROM? Why a huge ROM? It makes no sense in combination with a SD card. A SD card will take much more data and programs as a huge ROM. And it is very very fast with SJLOA...

Simply you could use an Eprom Cartridge for this. - Eprom cartridge are simple to create by modifying an old game cartridge (replace ROM) - You can wire it yourself using an " 8 Bit baby " Otherwise you can use an FE3 cartridge. FE3 has Flash memory on it, you can reprogram it simply with ...

The Ultra Vic-20 Cart is being created by fsporsche(Fred Santos) It will have every program ever made for the Vic-20 with a plus feature of a SD/Card reader built in. So you will have a very big ROM or Flash on it? Or do you mean, "every program ever made" are on SD card, like my FE3 card?

Boray is right, A0 files are simply normal PRG files with first two byte missing. You can detect it also by looking for exactly filesize is 8192 Bytes. For running on a real VIC you will need a RAM expansion on $A (block 5). Sometimes you will need a RAM expansion with write protection (ROM emulator...

Look very nice! Source code isn't downloadable ...

A µIEC/SD is much cheaper as a MegaCart. I would buy a µIEC from Jim Brain.

And I wouldn't sell a MegaCart! Even if you have a µIEC, a MegaCart is a verygood thing.

I have both and a FE3 with integrated µIEC and I wouldn#t want to miss any part!

Defectlive kernal are rare on VIC.

Yes. Only games which don't use BASIC. Are there any games which use BASIC?


901460-03 is the Char ROM, not BASIC and not kernel.



VIC20 BASIC ROM is 901486-01
VIC20 Kernel ROM is 901486-06

I had same screen on my VIC, it was the BASIC ROM. I replaced it with an Eprom and it works up to today.


Did you test your VIC with an autostart game (game cartridge)?

You only can detect if it is pressed (key down event). You cannot detect if it is hold nor it is released ...

D64 support removed!

Maybe a car racing simulator?

Each of the 3 devices use same firmware (SD2IEC firmware). But different people made a hardware (PCB) for it. First there was MMC2IEC. It was created by Lars Pontoppidan at the beginning of 2007. It started as a port of the PIC-based 1541-III to the Atmel microcontroller family. Shadowolf released a...

Thank you TLR, will test it later.


Is the broken monitor working again? Breakpoint set/reset with mouse wasn't working in my current version.


EDIT: Yes it working fine now, thank you again!

C64SD is same as µIEC and SD2IEC.


Maybe (I'm not sure) C64SD doesn't fit into VIC-20. It is made for C64 and I'm not sure VIC-20 has same distance between IEC and Tape interface.

You can use a 1571 to transfer files? Yes. A 1571 is able to read and write normal PC disks cause it has two disk controller, so it can handle GCR and MFM. I have an old PC with a 5.25 floppy drive. Can you explain how this is done? Do you just write to the disk from PC and read it from the 1571? I...
