Thanks for the compliments.

 

Any luck with the binary from the CC2 owners out there? I've double checked the colour cycling code on the title screen and it looks OK (but I would say that :lol:). Obviously theres something very small I'm missing thats stopping that part from working on the real hardware.

 

On the RAM cart front I'm about 70% the way through entering a schematic. I should have that done tomorrow and then I can order some parts and wire wrap a prototype.

No luck. It seems exactly the same.

Works fine on the emulator.But on a real system,i cannot see any sprites.I also checked WASP with my PAL systems.On PAL,there is the same problem.

 

Thanks for testing it again Walter. The RAM cart is about 90% drawn up now. Hopefully I'll get some time this evening to finish it off and order parts.

Edit 2: With the ProSystem emulator (1.3d), the emulator does not rely or require the 7800 BIOS file and there is no Atari Logo start-up screen. It results in the game loading right to the title screen. However, it does not respond to any input at that point.

Yep! Agreed. I've just tested this myself. However, I don't think the emulator is doing the right thing because that part of the game's code does work on real machines.

Whoops! Too quick on the draw there :(. The latest emulator version highlighted a bug in my code :). Find attached binaries to work on ProSystem emulator v1.3d :-

Wasp_05_04_09_1.04.a78Wasp_05_04_09_1.04.bin

The RAM cart is coming along but going slowly.

Ahh someday another New Game on cart! You are great!

Nope, still the same problem. You might try looking at the old thread for Sensodx 7800 as it seems like it had a similar issue.

Thanks for trying and the tip. I've searched on the forum for Sensodx and its not given me any eureka moments as to what might be wrong in my code :(. I'm going to come back to it again in a few days after the dev cart has been built.

Where did you order this thing from? I'd love to have something other than my CC2 to use. BTW I just ordered the 7800 Dev Board with ST docs and software plus cable. Now I get to learn to program like they did in the 80's! :D

Erm... I designed it! Its got a microcontroller to communicate USB and it programs the flash too. It can't program the flash while the cart is in the 7800 tho :(. Its only 32K as well. Hopefully it'll be up and running next week and I can try and get the game going on real hardware. I'll put some piccies up when its been made and tested.

 

Good luck developing on the ST. I recently dug mine out of storage and it it still worked after not being used for over 10 years. I won't envy your build/test/debug times tho. :lol: They are going to be sloooooooooooooooow! I think you need a hard drive for the ST dev kit too.
