Although im proud at the user interface that GFX offers the programmer, its
100% Euphoria code.
No machine tricks, etc. Well, yes I do the copying myself, but i dont use
any asm code, other than the wait-retrace. (because I have to have a quick
response on this one) .. but for me, wait-retrace doesnt need to be on.
In some cases it does though.
But indeed ememcopy is off course much faster, esspecially when copying
screens larger than 320 width. And not to mention the completely different
sprite technique used.
If you read the docs about ememcopy carefully, you'll even find command
lists as I suggested back then. My excuses go to Bolin for this. When I
asked him for ASM routines (like this) he nicely wrote them, and I never put
them in real use. But it seems the rest of the world did, when he gave them
out.
BTW, You may want to check Pete's new engine out called Neil. It supports
all Vesa modes, including bit depths upto 32.
