GroovyBee Posted February 6, 2010 Share Posted February 6, 2010 Got this working a few hours ago :- G2FSlideshow.06_02_10.1.00.a78 G2FSlideshow.06_02_10.1.00.bin Basically its a slide show of 3 images converted using an A8 tool called Quantizator into G2F's *.MIC and *.COL files. These two files are then run through my utility and the output is hand stitched together and built into a ROM image. I'm not going to post the images because that would give the game away . CC2 owners will need the following information :- 7800_48K 78BIOS I'll be adapting the tool to produce a fully automated assembly language file that can be built into a ROM. Hopefully this will mean that 7800 game title pages will get much more interesting . There is a visual glitch (1 pixel high) at the very bottom of the images. I don't know why its happening but I'll investigate and remove it if possible. Let me know what you think. 2 Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted February 6, 2010 Author Share Posted February 6, 2010 I forgot to mention that it won't look right on PAL machines. I don't have a PAL palette to give the A8's quantizator tool . The image is steady but it just looks horrible. Quote Link to comment Share on other sites More sharing options...

Remind me to send you some good Dracula images in case you want to include a digitized image of him in your halloween game! I don't know what it is, but I've always loved seeing digitized images on older 8-bit machines. Must come from when I had ComputerEyes on the Atari 8-bit. Anyone else have that one?

If you download G2F (from the link in the first post) its an art package that allows you to draw in 2BPP (MARIA 160A mode) and a maximum of 4 colours per horizontal line. When I get some time I'll see how many sprites can be overlaid on the image while the colours remain stable. Might make for an interesting game or three . 1 Quote Link to comment Share on other sites More sharing options...

Just the sort of mood I'm sure you were trying to create. Wow! What a response! Due to the fact that the current 7800 emulators don't emulate MARIAs CPU halting DMA the tech demo has to be seen on a real machine in my opinion. It doesn't really matter what the pictures are. Ilmenit (the author of the Quantizator tool) deserves the credit for writing an excellent conversion tool that makes that possible. What matters is the fact that the 7800 can now do something the A8 computers have been able to do for ages. 2 Quote Link to comment Share on other sites More sharing options...
nonner242 Posted February 7, 2010 Share Posted February 7, 2010 (edited) OH OH, Me me me ,me! I know what it is...... I really like that game! I wonder how many total images you can put on a normal 7800 cart. Also I think it would be VERY cool (hint...hint) to put a Movie Clip on a cart...which CAN be done with this... Yeah that would be my idea of Awesomeness... Edited February 7, 2010 by nonner242 Quote Link to comment Share on other sites More sharing options...

Yeah that would be my idea of Awesomeness... Its about 11K per frame (worst case - 4 colour changes per line). So a 512K cart would hold 46 frames.

Crazyace Posted February 7, 2010 Share Posted February 7, 2010 The first 2 images look pretty green on my 7800 (pal) - is the slideshow designed for PAL or NTSC? Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted February 7, 2010 Author Share Posted February 7, 2010 As I mentioned in Post #2 I don't have a PAL palette for the Quantizator tool to target . I can probably write something that will map the NTSC colour index into the PAL equivalents in the conversion utility. Its not going to be pretty because PAL has more blue/green than NTSC and NTSC has more yellow/brown. 1 Quote Link to comment Share on other sites More sharing options...
miker Posted February 7, 2010 Share Posted February 7, 2010 Just ran it... and really haven't felt in love with 7800. Apparently 7800-related version of G2F is required. Time to ask TeBe, eh? Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted February 7, 2010 Author Share Posted February 7, 2010 Just ran it... and really haven't felt in love with 7800. There is always time to convert you . Apparently 7800-related version of G2F is required. I'm going to try a few more things before I request anything. The 7800 can display 4 of 256 colours per line unlike the A8s which can only do 4 of 128. Time to ask TeBe, eh? I'm making a list! . 1 Quote Link to comment Share on other sites More sharing options...

I guess I need to find a NTSC 7800 somehow The 7800's PAL palette is not that bad. It would have been better with an extra shade of brown/yellow/gold instead of all the blue/green. 1 Quote Link to comment Share on other sites More sharing options...
ZylonBane Posted February 7, 2010 Share Posted February 7, 2010 Seriously - was that really necessary? Yes. That sort of "Tee-hee it's a secret tee-hee!" behavior must be crushed with extreme prejudice. If he really wants to show something off, then he should just show it, not make people jump through hoops. It's (unfortunately) a common enough behavior in modding communities that I have a pre-existing antipathy to it. 1 Quote Link to comment Share on other sites More sharing options...

If he really wants to show something off, then he should just show it, not make people jump through hoops. You clearly don't appreciate the fact that the current versions of the 7800 emulators do not behave correctly with MARIA DMA and CPU interaction. The ProSystem emulator would allow you to change all 12 colours per line in 160B mode and the result would look fantastic in the emulator. However, there would not be enough available CPU time per video line on the real hardware to do it. Therefore posting images taken from the emulator when you start pushing the machine is a complete waste of time in my opinion. I don't have anything against the authors of the 7800 emulators because they are easily good enough to play the back catalogue of games produced for the system. How long before they can't cope with new games that push the machine I can't predict . However, I'm sure we'll get close to a cycle accurate emulator in the future. 2 Quote Link to comment Share on other sites More sharing options...

I think the author of the ProSystem emu is working on a major rewrite. Also, Art Krewat seems to be taking in interest in updating the 7800 driver in MESS. So maybe 7800 emulation will be seeing some major updates in the not too distant future. I'm sure 7800 developers will appreciate that. Too vague...I dont even get it, and I know it!
