I have the following carts and I would like to make a ROM image of them to share with others if possible.
UMI Wordcraft 20 (16k ROM)
UMI ViTerm B [16__]
Kantronics Hamtext Client for amateur radio.
AEA-SOFT MBA-Text VIC-20 PROM Ver 1.0 SYS40969 to start
I also have a cart for a C-64 called Mini-Jini which was a database program. Is it possible to make a ROM copy of it and have ot run on a Vic-20? The instructions reference the Vic more than the C-64. Any help would be of help/
Thanks,

Concerning Wordcraft, generally, the answer to your question is yes.I have the following carts and I would like to make a ROM image of them to share with others if possible.
However, as with all things in life, there are exceptions.
Only a close inspection by qualified people can tell if there is some form of special copy protection in there.
This Wordcraft probably has a manual in which it may be indicated how to use this cart along with memory expansion and this may reveal exactly what memory areas it uses.
The other cart, on the other hand is for the 64 and should be considered incompatible.

Re: Vic-20 Cart info.
A ROM dump of a C64 cart will not work on a VIC 20. The two computers use the same microprocessor (more or less) but the memory layout, screen addressing and size, etc., are very different between the two. This means that the program would have to be rewritten before it would run on the VIC.kc2ykn wrote:I also have a cart for a C-64 called Mini-Jini which was a database program.

Assuming it's a machine code program, you'd have to disassemble the program, find out what every part of it does, rewrite everything that would have to be done differently on the VIC, and then assemble it into machine code. This would be quite an undertaking. Similar things have been done before so it's not impossible, but you'd need a very good understanding of 6502 machine language as well as of the architecture of both computers in order to pull it off. Not to mention a lot of spare time to devote to the project.
