Help for testing in real hardware
Hi all. Recently I've uploaded the official CVBasic compiler v0.6.0 with support for Creativision. It works just fine in emulation, however, it hasn't been tested in real hardware so far. I would be greatly interested if someone could test some of the following games in a real Creativision. I'm look...

Re: Greetings from Mexico City!
You're welcome!
I'm glad I could make this port. It wasn't easy but it came out really well.
Pretty happy to hear people is interested in CVBasic. I hope to see more new games!

Re: Recover damaged CPU Diagnostic ROM
You wouldn't believe this, but I think the Creativision Emulator has a bug. It enters in a loop when doing DEX, and when X=$20 it changes to X=$FF so it never ends the loop. I revised the source code, but it looks good. You can test it yourself by running it in trace mode (the -t command line option...

Re: Recover damaged CPU Diagnostic ROM
I just noticed my recover.c utility was prepared when I though the whole ROM as 4K, here is an updated version.
BTW, when you run it, you can notice the runs of bad bytes in the dumps.

Re: Recover damaged CPU Diagnostic ROM
That's exactly what i did. Only bit 6 and 1 of each byte. The 4K dump was the best there as only bit 1 was damaged, but it provided only 2K of $a000-$a7ff and 2K of $b000-$b7ff. However, there were a few parts of the dumps where several bytes in row were more severely damaged (runs of 5 to 10 bytes)...

Re: Recover damaged CPU Diagnostic ROM
I've posted it first in Atariage, but I solved the challenge. First, I made a program to make a "good" ROM based on three of the best files provided (the best one is the 4k image file, a shame it is only half of the program). I thought I could get something working, but of course, it wasn't so easy....

Re: Greetings from Mexico City!
I used to publish a list of authored games when introducing myself, but now I only mention two or three related games.
Nice to be in this forum. Thanks for the heads up!

At the end of February 20...
