It may be broken, or just not compatible with Mega STE adapter. I have here couple Quantum drives which are OK for sure, but dosn't work even with TT.

Yeah, really confusing. OUT would be jumper out - so no jumper, IN - jumper in place :D What is important is to set ID properly, so ID0-ID2 - no jumpers for ID=0, what is default by Mega STE . And need to put jumper to E7 to disable parity. If your drive hasn't it - bad luck. Will not work with Mega...

It is worth to add that there are 2 basic ways for undraw sprites when background scrolls, or just sprite changes pos , shape on screen: That is related with scrolling, because drawing background will 'automatically' undraw all sprites of moving objects. So, if it goes enough frequently, like 15 fps...

I really have problems to understand what he says in many cases - subtitles would be welcome
Or he should stay at French and there would be version with translated to English speech, by some pro .

If you use less colours with world map tiles, does that help speed up scrolling or does this only apply to screen copying commands? Less colors will surely make it faster. For instance Uridium uses only 2 bitplanes for background - and that's enough, since original was not with more colors. If scre...

I think that possibilities are endless. Doing some sprite support in Shifter would be C64-ST hybrid - I guess Tramiel would like it :D But need to be realistic and not going into some very complicated and HW demanding ideas. ST is enough fast to deal with sprites with CPU and blitter(edited). Agree ...

In case of horizontal scrolling on ST without blitter main problem is that required shift operation is slow with 68000 CPU. Shift means moving all bits in word (16 bits) for certain count of bits left or right - what is basically the horizontal scroll. Best way to avoid slow shift during game play i...

https://youtu.be/L32F68bGxms Fast paced drive with good framerate. There is some shooting too, for those who can not without it :D This was interesting for me, because first, 1988 release crashes right after play start with TOS 1.04, 1.06, 1.62 . It was corrected in Power Pack release next year, but...

Chunky with palette makes best sense I think. I guess 2 bytes per pixel for 256 colour palette. so 16bit packet equates to 2 pixels like $1122.. 16bit "true colour" would need a lot of bandwidth power, or as said earlier, would need a frame buffer to allow "slow frames" to be drawn.. may only be us...

8 bits/pixel of course palette based, as is in most cases. And indeed 12-bit palette, as by STE or TT . More wouldn't harm
Direct color has sense with 16 bits/pix or more .
