Re: Arcade versions of Dr Mario (Pill Dropper MD) and MegaTris

One thing I thought I would mention for anyone trying the game. Make sure you move the PLevel to 3 , 4 or 5 when playing. ... Well, that certainly did lower the difficulty from level sheer lunacy to a rather friendly just about impossible. Trying (Struggling? Blundering?) to play on Student :lol: I...

Re: Insane Contraption

The adventure continues, now also using the 32K SRAM system. I sorted out the differences, now I have code (including video mode) which is running on both. So one further step forth. IC32_test.jpg There is quite some clutter on my desk :P The metal box below the TV is an actual E-Uzebox (with an SPI...

Re: Hi to the UzeBox community

Neat stuff, thanks for posting! Could indeed be an interesting opportunity for those who would like to pick it up assembled! Any thoughts? Particularly in the bootloader? Not like there is much opportunity to do anything with it (there is only 4 bytes of ROM left I think), but let us know if you fou...

Re: Arcade versions of Dr Mario (Pill Dropper MD) and MegaTris

The corner bug is still present... but a strange thing happened on one iteration of testing; while dropping a different piece (several pieces later) the corner spot cleared. Did you try it with the code as it was (by re-enabling those checks), or did you also correct them like I suggested? Like for...

Re: Arcade versions of Dr Mario (Pill Dropper MD) and MegaTris

In DrMario.c (from the top post), why the lines 1266, 1267, 1317 and 1318 are commented out? Even as they written now, they appear incorrect to me as the relation should be ">=" in them to avoid out-of-bound access. As the code is now, it would read past the array's bounds during attempting to match...

Re: Arcade versions of Dr Mario (Pill Dropper MD) and MegaTris

Nice, glad it seemingly worked out OK to fix the problem!

I might try to take a look at that code, maybe there is something there reasonably easy spot by another pair of eyes.

Re: Insane Contraption

Today I managed to complete (well, mostly) the hardware of IC32, the system with the 32K SRAM, powered it up, successfully uploaded some stuff to the ATmega. P1127218_sm.JPG P1127220_sm.JPG Actual software is still quite some way to go, but the hardware is hopefully ready now! (I still didn't connec...

Re: A few fun text adventures

A short while ago I developed a simple interactive fiction engine for the Arduboy which is also AVR based. I designed a basic scripting system for handling the logic. The Github repo is here: https://github.com/jhhoward/MicroIF Huh, it looks pretty simple indeed! I took a look at various pieces of ...

Re: Arcade versions of Dr Mario (Pill Dropper MD) and MegaTris

I have a thought why you could have that occasional glitching audio, something I experienced and "fixed" in my game ("fixed", well, did sort of a ground-up new kernel to the end, which naturally eliminated it). The problem is that the audio mixer is not quite interrupt-safe, if it interrupts the gam...

Re: Insane Contraption

If you have a parallel port http://www.lancos.com/prog.html Most modern motherboards STILL do have a parallel port - it is just as a 26 pin header on the board and not broken out to a DB25 on the backplane. Eh, I hoped for some dirty trick making an empty ROM somehow still appear as an SPM instruct...
