Re: mcd-verificator (CD core accuracy tests)

@Miquel
Correct. The cart can't emulate Mega CD when sitting on a 32x. The 6 32x-cd games cannot be played on it.

Re: mcd-verificator (CD core accuracy tests)

No, it does not emulate 32x. It supports 32x roms when using a real 32x device.

Re: Need some help with moving levels maps (SGDK)

I usually structure the main loop like this.

Code: Select all

level = 1;

while (1) {
  loadLevel();
  play();
}
So if you move to level 2, "level = 2; break out of game loop; fade out, etc etc".

Those backgrounds are really busy. Reducing their contrast would help a lot.

You may have to wait for the next hblank in your code. ------------- *>>> >>>>>>>>===== ------------- Pretty ascii art. Say the h irq fires at *, which is too late for your code to hit hblank.

Re: Best solution for anime VisualNovel

I suppose you could interleave video and lower quality audio in the normal 1x (150kb/s) read rate, though with the finicky system each cd hickup will mean a small freeze then.

Re: Proper USB power mod for the Megadrive 2

Beyond the cd issue, I don't think usb gives enough power? The original PSU was something like 10V 1.2A = 12W, while usb only gives 5V 0.5A = 2.5W. Maybe you're connecting to a standalone usb charger rated for 2.5A, using usb charging cables (not regular data cables!), but that's a slightly rare set...

Re: Convert PCM to XGM

I suppose he wants to emulate a WAV using either synth or PSG, like those ancient speech synthesizers did. It'd sound bad/metallic/robotic/etc, and I don't think any such kit exists for Genesis.

Re: Aseprite Mega Drive Digitizer

Software solution to a hardware problem ;) The quick solution would have been a composite out for your computer.

This is still cool, and one more use of the usb connection is good.
