Moon Cresta 7800

Recommended Posts

25,920 clocks (at 216 scanlines) w/o overhead on 1BPP - Jeebus. MARIA is what some odd 3Mhz, but I guess the DL/DLL overhead is a real killer, especially because of DMA. I might be getting that wrong though.

 

MARIA clocks != CPU clocks. You need to divide by 4 to get the CPU cycles lost.

 

MARIA is clocked at around 7.16MHz. DL/DLL entries aren't much of an overhead. They are stored in RAM and are accessed at 2 MARIA cycles per byte. DL entries are 4/5 bytes so take 8/10 MARIA cycles.

 

Well, crud. Color is a real killer for me, if I can get 25 at 160 but 9 at 320, I guess I'll have to stay in the low res realm. I was really looking forward to that too (hi res level, low res sprites w/ more color). I know I can do tricks to squeeze in more colors, but I'm just plunking around right now - kinda too advanced for me right now. BTW, what is the max (visible) vertical res in 160?

 

There are sprite and character mode examples in the 7800 programmers section which would be a good starting point. You can go a long way with programmer tricks to change colours. For example, my Halloween themed game can display 64 colours on screen at the same time.

 

Anyways... I think we've thread jacked enough. Feel free to start another thread in the programmers section if you have more questions.

Bummer, looks like I missed out :(

 

Given that there are usually a few people that don't come through on their purchase request you may want to ask Bob to be on the standby list in case any spots open up.

Guess i missed the window.. a bit funny because I've been on reserve for a few of PMP's projects that have been delayed because of technical issues with the XM and compatability, but when one is made available to order, I manage to be preoccupied with other things. If any there are any left over for whatever reason, I want dibs! :P

 

Will we be able to get these through the AA store in the future?

Hi Guys - ok everyone that has paid me this far has their games going out on Monday (They've already been mailed; but being that it's late Saturday nothing will happen until Monday anyway).

 

Thank you!

 

Bob

I'm interested in being in the later adopters/second run of these. Moon Cresta was one of my favorites back in the day, and I'd like to have a quickie option to play it again that doesn't involve a freakin' emulator and my computer.

Hey Bob. This is beautiful work.

 

I've been away and just saw the list and price. Please put me on your backup list should you make more.

 

 

Million thanks.

Hi Bob. Never played Moon Cresta before and tried it out.

 

This is a fantastic job you have done. I'm getting hooked on this shooter.. Will you be having any more carts available? I know it's a little late for a request but thought it don't hurt to ask.
