Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)
Thanks, Tormod, I'll check that out. Maybe I can get one rom or another working.

Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)
No, there are more rom calls. Gameplay starts, but the resolution seems to switch into a wrong mode. Eventually the program freezes. My hex editor showed some more JSRs and JMPs into rom. A few more changes are required. Does anybody know a complete documented rom listing for kernal and Basic, like ...

Re: Introducing: Dragon multi-cartridge for roms
Thanks Rink :oops: his game choices are a little dubious Yes indeed. I'm not through, examining all available roms, so I simply put 32 "random" games on the eproms. I don't know the games, but I noticed, not all games are really, ahhmm, "great" games. I suggest, you simply reprogram the eproms somed...

Re: Toolkit by Premier Microsystems, pics and pdf.
the one thing that I'm not sure of is how to ensure the PCB is cut to shape; I used layer 20 "Dimension" in eagle. iTeadStudios CAM-job did the rest. The eprom programmer I'm going to get is the SIVAVA Willem EPROM Programmer PCB50B, it was mentioned in a post in one of the other sections. I've got...

Re: Diagnostic Rom: wrong image size
Yes, obviously it is a 4k cartridge. The rest of the file is garbage.
For my multi-cart however I need 8k images.

Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)
Thanks tormod,
I changed the address of the JSR and cut off the upper 8k. The modified image now runs with xroar.
I'll try tomorrow on real hardware with my multi-cart.

Re: CoCo cartridge Atom (1983) (26-3149) (Tandy)
Game seems to run flawlessly. No, it does not. Title screen and "intro" are ok. When I start the game play, the upper half of the screen fills with garbage. The lower half shows running counters and something moving. Graphics error or a special graphics mode? Same with XROAR, same with original rom...

CoCo cartridge Atom (1983) (26-3149) (Tandy)
download/rom/CoCo/Atom (1983) (26-3149) (Tandy).rom:
It looks like that rom in reality is just an 8k rom. It contains two concatenated copies of the game ($000 ... $1fff and $2000 ... $3fff).
I cut off the upper half and tried it. Game seems to run flawlessly.

Re: Introducing: Dragon multi-cartridge for roms
Thanks, Alastair. Yes, the program can be started manually. I just wanted to say, that this is the only program I saw, that does not auto-start, like all of the the others. And I noticed, many programs can be launched via "EXEC" without address! They start anyway. I had not much time, but here is a ...

Re: Introducing: Dragon multi-cartridge for roms
Update on the multi-cartridge : I've learned, that not all programs are thought to be auto-started. Some development tools need a CLEAR x,y first, like the 6809 Editor Assembler or Dos Dream of M.J. Kerry. Compusense's Demon refuses to autostart. I could add an autostart disable switch or simply co...
