I spent a bit of time playing Valkyr this evening, and recorded my efforts.
This is the version from Geroge Beckett with fixes for the Minstrel 4th and RC2014 YM2140 sound card addressing.
This is a slightly loaded Minstrel 4th with a Jester Ace SD reader, Shiela Dixon's USB/serial keyboard interface, the RC2014 YM2149 sound card and Tynemouth Software's Boldfield compatible joystick card all attached via a RC2014 Backplane 5.
All cards used in loading and playing the game.
It's interesting that everything apart from the YM2149 is now standard on the Minstrel 4D Turbo.
