Crazy Ace.....your sprite ram buffer idea is the bomb!

It is the better way to do it. I did it using ROM for
now as I cant get any of these emu's to recognize
RAM at 4000...so I did a ROM buffer as a test and
it is much better because I can still use the indirect
mode as well for other back drop stuff too... nice advice!

Thanks !

It makes much more sense now that I've tried it.

That's cool,

I've been distracted by the A8 v C64 thread - so I haven't spent as much time coding .. I was going to test a prosystem a78 file with ram ( after you said it wasn't working )
The indirect mode sounds nice - but end's up wasting cycles every line, so it can be better to avoid it if possible.

Looking forward to seeing your game

That would be sweet if you could tell me how the RAM cart needs to be set up.
But I see that the sprites are much less taxing as you say. Now I only need
one character entry per zone per need, the 12 large ram buffer sprites and the
rest are up to 31 random sprites. I have seen no signs of slowdown yet either.

If you figure out that RAM trick it woud really open the door for more sophisticated
backdrops...well at least from my leel of experience. My guess is the right guy coding
this Maria chip would do miracles.

I would have loved to have seen the Maria as part of the STe if not the ST.
