Shouldn't we say 'Bug in MSXturboR on Zanac-Ex'? How can a game have a bug on a machine that wasn't released when the game was made Wink That doesn't sound fair to the game haha....

You have a point, but we'll know when someone finds out the root cause. The game could be doing something illegal that happens to work on (most?) MSX2 machines, but not on the GT...

Thrill and suspense await!

If despite this 'something illegal' the game works on MSX2 machines, I'd say it's still not a bug... In 1987 the game worked just fine on all the machines it was back then claiming to work on...

Did you test it on all these MSX2 machines to be able to make that claim then? Cool

What kind of bug are you talking about? I watched 3 times and cannot see any issues.

Just noticed it. It more like closer to the middle. The issue there is that it uses a screen split. So, screen accidentally stuck in VRAM page 1,2 or 3 instead of 0. Probably rare timing issue as screen rolls almost to the half of the screen before that happens.

Can you indicate at least the time code of the video?

Oh, It's near in the middle. Thank you, I had looked towards the end and therefore saw nothing.

Oh, sorry, I decided later to add another demo round to show that next time it looks okay, and I forgot that I did that Smile
