Silpheed (USA) Problem

Since the last core updates Silpheed no longer works on the Mega CD, when you press start it just goes to a black screen.

Used to work just fine, other CD games boot fine, just seems Silpheed doesnt.

The latest MegaCD core is a mess. Many games don't work. Revert back to the June 2020 core and you'll be fine

https://github.com/birdybro/MiSTer_Core ... 020128.rbf - test this one for me, it's one I just compiled with the latest commit from srg320 which rolls back the timer fix (which is the very likely cause of the issue).

The build posted above apparently fixes Robo Aleste's slowdown as well (just briefly tested it, seems fine now). Thanks aberu

I wonder if it fixes the minor slowdown in Shining Force CD when the SRAM is writing...

This loads both JPN/USA version of Silpheed.
