Un émulateur d’MSX par l’auteur de SegaLI.

– VDP: corrected vblank interrupt timing, it was 1 scanline too early
– VDP: improved render timing, updating the surface at the start of hblank
instead of at the start of the active scanline
– VDP: fixed screen 0 text colour 0 always being black
– Z80: if ld a,i/r is interrupted, the p/v flag is reset, thanks GuyveR800
– VDP: fixed a few small bugs with mode 3 sprite cloning
– VDP: fixed screen 0 border size
– VDP: corrected emulation of bogus mode 1+2(+3)
– Z80: made trace logger more user friendly, it’s disabled by default though
– mappers: fixed Irem TAM-S1 (R-Type) mapper range
– mappers: added ROM mirroring quirk to Konami types
– mappers: common MegaROMs are autodected by finding mapper register writes,
inspired from Marat’s fMSX
– mappers: removed Zemina ZMB type, no dumps exist in order to test it
– mappers: added optional extra settings per type, instead of all mapper types
being identified and auto-configured with a single id
– mappers: Konami Sound Cartridge can now be configured as Snatcher/SD Snatcher
type, or a modified board with 128KB RAM
– mappers: merged simple no-mapper types into a single one, and made the page
layout configurable, it’s even possible to create a hybrid ROM/RAM board
– mappers: rewrote ASCII MegaROM emulation, with support for about 30 official
boards, and any custom configuration, props to http://gigamix.jp/rom/ . Also
thanks to OeiOeiVogeltje, Quibus, BiFiMSX, Haohmaru for testing their carts.

– internal RAM size and primary slot can now be configured
– mappers: added Al-Alamiah Al-Qur’an type properly (protected/encrypted)
– added lumi noise simulation, for an answer to « wtf is a lumi noise? » watch

– VDP: corrected interrupt request/acknowledge timing due to a small delay
between that and accessing a VDP register
– VDP: added vblank interrupt/flag suppression quirk when reading the status
register at the same time the vblank bit gets set
– VDP: added Toshiba T6950/T7937A model
– added a firmware downloader, for indirectly obtaining essentials, such as
BIOS files, this will also check for meisei updates
