Cyprian Posted September 25, 2018 Share Posted September 25, 2018 If Im not wrong, there is so called 'blitter' unit integrated into Suzy chip. Do you know which hardware registers belong to it, and how to program them? https://git.m4xw.net/Switch/RetroArch/libretro-handy/blob/develop/lynx/lynxdef.h Quote Link to comment Share on other sites More sharing options...

vince Posted September 25, 2018 Share Posted September 25, 2018 If you understand french, I suggest you to have a look to my translated version of the epyx doc (here for the sprite engine) and the memory listing (here to display all) Quote Link to comment Share on other sites More sharing options...
Cyprian Posted September 26, 2018 Author Share Posted September 26, 2018 (edited) 42bs, vince thanks for those links, they are very useful. Unfortunately I can't see any mention about 'blitter' there. Does it mean there is no such a functionality in Lynx? I mean such a functionality like ST / Amiga blitter has: copy/fill/shift/mask a block of memory.

oziphantom Posted September 26, 2018 Share Posted September 26, 2018 The "sprite" ( of which there are none ) engine is the "blitter" engine, also called Suzy. It has the normal, EOR, with transparent colour, to/not collision buffer, Stretch, flip etc. There is no generic "blitter" as in AND OR this part of RAM like the Amiga Design.
