<n_n> mirrored mode however is known not to work on toshiba vdp
<n_n> to clarify
<n_n> mirrored mode = screen2 with a mask on the pattern or color table address to make it use less than 3 separate tables
<Quibus> mirrored mode doesn't have a test in ident.bas, right?
<n_n> it does
<n_n> it's the 'do you see this text 3 times?' test
<Quibus> mirrorred mode works always, except on Toshiba MSX1 VDP's?
<n_n> yes, it works on v9938/58 too
So, also testable with ident.bas. openMSX doesn't emulate this difference at all.
