r005.8.11 Scanlines
r005.8.11e Scanlines - experimental/ fork (see experimental folder in amstrad core folder) *





*experimental version is a fork, better in some games (Arkanoid, Pinball Dreams PREVIEW), worse in some other ones (Saboteur2, Tetris95)

* r005.8.12 : Quasar CRTC Diff. CRTC1 detection ok : From Scratch Vanity (but crach) Still Rising Vanity does run (but -Pulpo does crach)
* r005.8.12e : experimental fork (same way of fork, just a boolean) - From Scratch Vanity does run, -Pulpo does run also.
Better feeling in games.

r005.8.13 : better CRTC1, and better VRAM, better in Still Rising Vanity (cool !), PPI overclocked (because it is not clocked PPI...)
r005.8.13e : Arkanoid 2 running fine on experimental fork.


What's the compatibility rate these days?
I don't know, but it's feeling nice, I succeed in merging all my last version, so I shall reach an "over-testable version" candidate promptly.

r005.8.14 : GA WAIT_n generator revisited :
  • IO_ACK trigger in edge, not in state (better in some scrolling...)
  • WAIT_n generator ignoring M1 while IO_ACK
  • OSD entry : "MEM_wr" mode : quick or slow. quick by default.
quick : Arkanoid II, Prehistoric II. Ecole demo. Pinball Dreams
slow : Saboteur 2. Still Rising demo.


and CRTC0|CRTC1 choice (CRTC1 by default)

r005.8.14.1 : TV mode using VSYNC/HSYNC xor and Gerald VSYNC/HSYNC width formula.

 This version was realised with atari forum team, testing several experimental forks.

 It does output 15kHz original signal on SCART. Do use mist.ini scandoubler_disable=1 (see http://github.com/mist-devel/mist-board/wiki/DocIni)

 Sorry FDC work will be for a next time : my r005.8.15 candidate version does fail 80% of arnoldemu FDC testbench...  :picard:
