I can confirm this: both component progressive and RGB interlaced pictures are well-centered! Unfortunately no picture if component is set to interlaced or via direct VGA out, perhaps the fault of my TV... Anyway, nice improvements in terms of compatibility!

Thank you slingshot! :cheers:

Finished the SuperGrafix port from MiSTer. For the increased demand on memory bandwidth, the SDRAM clock was increased to 126 MHz, hopefully it won't be unstable (it's still in spec, MiSTs should have 133 MHz SDRAM).

The FPGA's internal BRAM usage:
M9Ks 66 / 66 ( 100 % )
So don't expect many more improvements from now :)

PS: rename SuperGrafix ROMs to have an .sgx extension, and load them via the 2nd menu option.

:cheers: Good work !!!

The SuperGrafix games are only 5, am I wrong ?

I tested the last Madou_King_Granzort_(J)_(SGX) and desn't work on my system. Could someone test it ? Thanks.

It starts for me.

I see 6 games:
1941
Aldynes
Battle Ace
Darius Plus (it works on a regular PCE, too)
Ghouls'n'Ghosts
Granzort

Cool work. .sgx seems to work fine on my v1.2 MiST which had issues with (now fixed) Cores which had memory speed issues. So 122mhz should be good for everyone.

There's a seventh Supergrafx Game. Darius Alpha is a Boss Rush version of Darius Plus and also has Supergrafx support, I just tried it and it also works fine like the other six games.
When I loaded 1941 for the first time, I just got a black screen, this didn't happen again (tried all games several times now), so I guess it won't happen again.

Thanks to all involved for this great update!

On the PC Engine core for MiSTer there were two games that didn't work: "Andre Panza Kick Boxing" (bad graphics) and "Davis Cup Tennis" (crashes when you start to play): viewtopic.php?p=353575#p353575

Since this is a port from the MiSTer core, I assume it is the same on the MiST. Fixing these bugs might be the last step needed to achieve 100% compatibility.

Superb work as usual slingshot, thanks. Great to see the MiST having such a great version of the PCEngine. So many great cores on the MiST! 8)

CD games? I don't see it mentioned, so I'm assuming that's not implemented.
