I recently upgraded my laptop to Ubuntu 18.04, and found out some emulators, such as Gens would not work. It doesn't appear that there are any recent packages, so I forked this, and setup some auto-building, TravisCI magic. https://github.com/kubilus1/gens/releases Installation instructions for 18.0...

Trust me, old CGA RGB monitors were not uncommon. The cyan and magenta is permanently burned into my brain and many others. But yeah, interesting idea about alternating the checkerboard pattern. That should get rid of the horizontal banding that occurs when checkerboard is used in composite mode, as...

Also with something like 8088mph ( https://trixter.oldskool.org/2015/04/07/8088-mph-we-break-all-your-emulators/ ) running CGA in composite mode is pretty much the least likely way that old DOS systems would be used now or back in the day. It's still a really cool demo and it's fun reading about how...

I mean, I started off like that as well. (S-video modded Genesis 2 "3/4" board) But some of the effects you see in a variety of games (see above link) show that the intention of the hardware is to *not* be in RGB mode and to utilize color artifacting to some degree. Is this used as a primary means o...

PAL actually doesn't look as bad as I thought it would there.

Not dithering, but horizontal striping. On my system, I don't see rainbow artifacting, maybe I would in larger swaths of colors, but some of the colors do not match exactly what I see on the emulator, which is not a surprise. This technique was used quite a lot on older computers, along with quite a...

No highlight or shadow was used either, so theoretically this could be increased a bit using those techniques. https://raw.githubusercontent.com/kubilus1/blast/master/examples/comp_test/216colors.png Just some simple fun playing around with NTSC color artifacting: https://github.com/kubilus1/blast/r...

Okay figured it out. I have to check this during hblank. I setup an interrupt and that seems to work.

So I figure I can grab the vcounter when a collision is detected and know where vertically a collision is happened, more or less for free.

What I don't understand is that in this simple example, very little is going on. Basically, move sprite, VDP_setSprite, VDP_updateSprites, check collision.

No other methods are being called.

Yeah, alone I realize that it is far from enough. But aside from being annoyed that it is not actually working correctly, I figure I may be able to take some kind of advantage of it. For instance, let's say I use the collision detection method where I indicate which column each sprite is in. Then as...

So when, am I supposed to test the Sprite collision flag. I can't seem to get this to work reliably without adding a crazy amount of "delay". For instance, if I take the old basic sprite example and test for collision, this does not work unless I loop over the test about 1000 times. For example, I w...

What about running the out.bin in an emulator? Does that work?

cd cp gendev/sgdk/skeleton . ... should be cp -r gendev/sgdk/skeleton . This means the boot dir wasn't copies and is likely wrong. I don't have a convenient way to verify this on real hardware ATM, but I could see this leading to a blank screen. First step would be to verify on emulator perhaps. Fy...

Setting winecfg to Windows 7 seems to work. Appears to work fine on wine!

Doesn't seem to allow installation in Wine. "The operating system is not adequate..." Is this looking for a very specific version of Windows?
