This is an Cartridge for your C64.

Homepage: Universal Cartridge 2 – (oe7twj.at)

It can hold one or more programs (up to 512K FLASH) and start it using a program list.

The UC2 can:

run a 8KB Cartridge

run a 16KB Cartridge

run a Ultímax Cartridge

run a PRG File which start with RUN (Load address $0801)

run a PRG File which start with SYS (Load address anywhere)

Cause UC2 has RAM it can load programs also from a disk drive or a SD2IEC and start it as Cartridge.

UC2 RAM can be write protected so it is like an EPROM.

For the FLASH any 128K, 256K or 512K Type can be used (for example AM29F040).

The UC2 cartridge can be configured fully using IO register at $DExx.

It can control /EXROM and /GAME so C64 know which kind of cartridge is mounted.

You can disable the IO register and make the cartridge fully invisible (up to next hard reset).

There is a command line tool (UC-Tool) for Windows, which can create Image Files for the UC cartridge. Simply copy CRT or PRG files to a directory and create a small textfile (CSV file). UC-Tool will make an Imagefile for your EPROM prgrammer (for example TL866). CRT files are Cartridge Files for VICE (only Typ 0 allowed: 8K, 16K, Ultimax). PRG are files you can LOAD and start with RUN (OneFiler).

There is also a file browser (modified FB v2.0) which can load and start programs from a disk drive or an SD2IEC. The difference between UC1-FB and the normal FB is, UC1-FB can load and start CRT files directly. CRT files must be type 0 (8K, 16K or Ultimax). After loading the CRT file it will be copied into UC1 RAM and started with a Soft Reset.
