Hey this game is pretty cool, can't wait to see where it ends up!!

 

Good job!

@the.golden.ax and AdeptRapier

 

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 ). 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.

I haven't got a 7800 setup right now so I can't check it on a CC2, but will soon.

No luck. It seems exactly the same.

Yea its not working for me on v7800 either The game sounds fun, cant wait to play it!

I just tried "Wasp_04_04_09_1.03.a78", works fine in ProSystem 1.3c. Neat little game, needs some more variety though.

Hope you keep working on it.

[+GroovyBee]

Thanks for all the testing. Looks like the next update will be after I get the RAM cart going. Sorry folks .

Hi Groovy

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.

greetings Walter

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!

[+Mitch]

The new version still has the same issue on a real 7800.

I expected as much . I can't investigate it properly until I get the RAM cart going.

Soon...

Some minor fixes. Its my last attempt to get it going on a real machine before I get down and build a dev cart :-

 

Wasp_07_04_09_1.05.a78Wasp_07_04_09_1.05.bin

Reports from CC2 owners much appreciated.

[+Mitch]

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.

[+Mitch]

I found the thread I was thinking about but after re-reading it I'm not sure if it applies to your issue.

The parts are in to build the homebrew RAM cart now. I say RAM, it turned out to be a USB programmable flash cart in the end. . The RAM cart was getting to be as complex as the CC2. Hopefully I'll get some time to build it this weekend.

[the.golden.ax]

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!

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. They are going to be sloooooooooooooooow! I think you need a hard drive for the ST dev kit too.

And for my next trick...

 

 

Its just a mock up so don't too excited . It also depends on the RAM cart proving if the game engine is viable. I have plenty of game ideas but not the time to code them all in assembler .
