Title: Asking for assistance !
Post by: Lone on 21:50, 03 February 14
Hello guys,


As you may knwo, I try to write a precise emulator, that can run demos correctly.
The CRTC 1 emulation seems fine (more or less, of course), but I run a demo which make me wonder about lot's of things, like meaning of life, whener god exists or not, or how syncronization works on the old CPC....


This demo is the Part 6 of "the-demo", called "ball ball ball". When I run it, depending on slight sync adjustement, I have the screen with the red scroller on top, or on bottom.


Can someone with a real CPC remember it, and tell me the truth ? Emu over there don't agree (and I don' own a CPC, which is, well, really frustrating from time to time)


Here you can find my result (with a grey bar which is a VSync bar)


A photo of it would be a great plus !


Thanks

Si j'ai bien compris, tu as 2 VBL dans l'écran ?


C'est juste programmé à la porc donc...


Par contre je n'ai pas compris ce que tu veux (j'comprend pas grand chose à l'anglais)... En gros tu cherches à savoir si sur un vrai CPC le scroll est en haut ou en bas ?


Dans le cas ou il y a plusieurs VBL, cela dépend entièrement du réglage de l'écran. On pourra à loisir se caller sur l'une ou l'autre des VBL...

C'est cela même : On a une zone de vsync en plein milieu (la bande grise sur la photo), avec laquelle on se cale sur certain emu... mais pas d'autre, qui se calent donc sur celle qui se trouve en bas (emplacement normal sur la photo).


Je me demandais donc, ce que ça donnait sur un authentique CPC.

En gros cela dépend de la tolérance et du réglage de l'écran...
