Re: CUzeBox - The new official Uzebox emulator

I honestly would like to hand this over - not necessarily meaning I wouldn't intend to do anything with it any more, but in my present situation I unfortunately just don't have the mental capacity to keep track of the emulator. It is nice that so much diversity of ideas exist around the Uzebox - but...

Re: M74 questions

That wasn't correct either, the c4bpph.c one just masks off the low 4 bits of the input. So if the input is 255 (0xFF) as is the case here, you would get 0xF. Mode 74 works with 16 colour tileset and sprite data, you need to give it such input. Converting to 16 colour of course can be done, but auto...

Re: M74 questions

You will need a 16 colour input image here, the palette of yours is the whole 256 colour Uzebox palette, where white is index 255. The converter treats all colours outside the 0-15 range as zero. So first create a palette of 16 colours picking those colours you would like to have in your game, and u...

Re: M74 questions

Attached Python generators for the 4bpp tile / sprite set and the 1bpp tile / mask sets. Should work (only checked the output visually). Palette is not generated in these. The 4bpp generators (4bpph.c and 4bppsh.c) generate the same tileset data, one was originally intended for sprites (the first M7...

Re: TinyNES - open source NES clone

I like the idea of this, neat little thing. Also would add that compared to finding an original NES, this one has all new components apart from the two original chips, so wouldn't have ageing or wear related issues possibly surfacing. So could be a nice thing for someone liking the idea of using the...

Re: cuzebox runs great on my TV box

A bit old thread, just maybe useful still. The performance of the emulator is dominated by two things in my experience. One is the AVR ALU emulation (on this my guess is that around a 700MHz P3 should be the minimum to do it), the other is getting the display data onto the screen. Surprising as it i...

Re: Insane Contraption

This PCB was very conservative with trace widths, so is quite inefficient overall indeed. Had a better one printed since, but didn't get there with motivation yet to start working on it. The idea with the daughterboard for the SCART is modularity: You could swap that to a board doing NTSC with the A...

Re: Outpost in the Dragon's Maw

Hi Clymax, nice, glad you gave it a go! :) This game has quite some tricks to get efficient with it, I tried to set up the difficulty ramp so it should hopefully be rewarding to try pushing things further! ;) And yes, the suggestion is valid, and was on my mind, unfortunately I miserably ran out of ...

Re: Insane Contraption

Looking around here I realized I never posted this thing. P6197489.JPG This is a direction where this thing ended up evolving, which I might some day complete. The system there is an ATMega1284 acting as Video and I/O, combined with a 32KByte SRAM (this part is the same as the solder-spaghetti-monst...

Re: Change my mind: plug-and-plays > kits, to attract gamedevs AND end-users

I think streamlining of the web emulation would go a long way. Personally I like Uzebox because it's niche, and the interactions here I find to be high quality versus what I see other places that have a lower barrier to entry. Not saying we shouldn't ease things to new users, just that there are 2 ...
