Re: Upcoming obscure video modes

Guys, I've had a hard time since last year with my mother suffering from a crippling stroke. I had hardly the time to do my regular job, there was no time for hobbies (like finishing my Würgertime game). Uhn, which "mode 11" we're talking about? However, the basics for "my" mode ...

Re: Problem with EUzebox

As an aside to this can you just hook up the scope to the xtal to see if it is oscillating at 28mhz. Careful with that, the on-chip oscillator is an icky beast. The extra capacitance of the probe will kill the oscillation (not the oscillator, just the "sinus"). You have to use a 1:100 osc...

Re: UzeSDL API Emulation Layer

Ive searched for a compiler option to handle this, but i cant find one. __attribute__ ((packed)) See http://gcc.gnu.org/onlinedocs/gcc/Type-Attributes.html Actually, anything passed to assembler code should be explicitely aligned and packed in the game sources, as it may trigger odd bugs which are ...

Re: Buy assembled Uzebox Brazil

Does your TV set support NTSC signals? IIRC in Brazil PAL-M is common, which is a mixture of NTSC's frequencies and PAL's odd/even line color alteration. See http://en.wikipedia.org/wiki/PAL-M.

Re: Video Mode 9 tile format

The instruction 0xeN0M means "ldi r16, NM", so the pixel data is in byte 0 and byte 1. The pattern for the other instructions is different because you have to calculate the next tile address, this is done step by step interleaved with handling each pixel. The data is sent to the port with ...

Re: uzebox emulator in (x) ubuntu 13:04 ...? (from Germany)

Den uzemdbg brauchst du nicht, den braucht man nur, um den Emulator selbst zu debuggen. Ruf einfach "make release" auf, um nur uzem zu bauen. Das sollte einfach so gehen.
