Re: new version of Uzebox (ATmega1284) coming?

...uses 8x4px combination tiles... Hmm, sounds like you are up to something interesting there, but I have no idea what ;) The mystical fog will lift this week, I hope. Currently fighting not to let the magic smoke escape on the same occasion. 8-) I'd be surprised if there wasn't some kind of ram ti...

Re: new version of Uzebox (ATmega1284) coming?

Does this apply to ATmega1284 or ATmega1284P (picoPower version) or both? That was for both. I extensively tested a bunch of them without success. Hmm. I have both a ATmega1284 and ATmega1284P in my stock. I originally planned to go with these, will have to try if they do. Lee's palettized sprites ...

Re: new version of Uzebox (ATmega1284) coming?

There was no work done on this in months and there's a couple reasons for this. First the chips needs to be "overpowered" to 5.6V+ in order for some of them to work at all. Does this apply to ATmega1284 or ATmega1284P (picoPower version) or both? Even then, quite a few would still have gl...

Re: Sound garbage with small demo

Full circle. What lefts me puzzled, it works now. Tests and WIP. Was it your kernel changes? :D :D :D :D :D :D IT WORKS! :lol: :lol: :lol: :lol: :lol: :lol: Thanks a lot for helping me. Now I can have 35 RAM tiles with my WIP and 30 columns, and sound. I'm going to implement the player sprite.

Re: Sound garbage with small demo

Does the test project we share back and forth exposes that 20 tiles limit issue? With -DSCROLLING=0, first errors are with 27 RAM tiles. With -DSCROLLING=1, first errors are with 41 RAM tiles.Same difference like my WIP: 14. Fyi, you can look at the kernel sources for mode 3 settile, there's the fo...

Re: Sound garbage with small demo

I've updated kernel source and recompiled. The SetFontTilesIndex() bug is gone. I tested with my WIP game, with -DSCROLLING=0 I can use up to 20 RAM tiles now, with SCROLLING=1 up to 34 RAM tiles. What's the big difference between the two modes? I found with -DSCROLLING=0, the .noinit section is mis...

Re: NTSC LCD screen at adafruit

Very good idea, but we have to recompile all games in this case... I thought that to be the easiest part of it. Most complicated is to make a nice casing for it. EDIT: I'd think unusual devices and using arcade boxes with JAMMA connector is the right way to go. As Harty123 wrote elsewhere, a lot of...

Sure. Because of the different mazes I see it as a sequel to PAC-MAN, not just a pink-washed version of it. :mrgreen:

Re: NTSC LCD screen at adafruit

I thought of connecting a standard "TTL" QVGA display to the uzebox to get a portable arcade. There are hundreds of such displays - TFT and OLED - out there, at extreme low prices. You even can dismantle old color display cellphones to get such a display for free. They usually have 666 or ...

Re: Sound garbage with small demo

Your test archive works for me up to 40 RAM tiles. With 41 RAM tiles it hangs. Same with my own test archive. With my WIP, the border is at 34->35 RAM tiles. But I have a new problem now. In my WIP, I use Print(), which produces garbage the moment I specify -DSCROLLING=1. Seems to be one has to subt...
