Uzebox Forums

Keep up with the good progress. Keen to see the finish product.

This completely lacks what I think makes the Uzebox fun. The strict limitations on CPU/RAM in the Uzebox makes it a challenge. I am a masochist I guess. If I am going to move on from the Uzebox it will probably be in the other direction and seeing what I can build with just 7400 logic. Also no 10nS ...

I don't use the generic video modes so I can't answer your question. I assume it is something going wrong with the font. There are functions in the API SetFontTable(const char *data) SetFontTilesIndex(unsigned char index); That have to be used before tiles can be drawn. Someone with actual knowledge...

Doing a full proper UART would be a lot of work. Making Uzem just spit out info to the console anything written to UDR and just ignoring the UART config and status registers would be not terribly hard. Cuzem supports the UART Interrupt Complete Flag as a pseudo timer for the RLE-mode/1337-Demo. It d...

You probably wont like my answer. A Spreadsheet and AVR Studio 4. Oh yikes lol. This seems like something a tool should exist for! Perhaps something that breaks the assembly into basic groups, like the graph view in IDA Pro, and counts total cycles for each group? Maybe I'll give writing one a go a...

<SNIP>meaning 243 visible per field instead of 224? There are only 224 scanline that the Uzebox draws. In fact you can set that to a lower number in most video modes with renderLinesCount and firstRenderLine. You could make the screen a bit more "letter box" by setting the renderlines to 186 and do...

Looks awesome. I might knock one up myself to have a play.

Back of napkin I think that sounds about right. The user loses control of the CPU the entire visible picture time (video and audio) and the Hsync time of the rest (for audio) There a 262 TV lines of which 224 are visible. That leaves 262-224=38 lines the user gets the CPU Of those 38 lines the user ...

Do you want NOT gates or do you want diodes for the "Blue-Luma" and "Red-Luma" channels?

Minus doesn't mean the same as plus-the-inverse does it?

I'm feeling pretty vague at the moment. The source was posted somewhere before but I can't find it now so here it is again. Here is a video showing some tanks if you didn't see that. https://youtu.be/PWnW5ROSPjI?t=695 Its got a LOT of ASM in it for the graphical stuff but the game logic and object m...
