Keďže ako Ikon poznamenal, sa táto úprava šíri len ústne, pridávam to aj sem.

ZXS +2A/+3 má vďaka inej ULA kompletne oddelené zbernice VRAM a hornej RAM, takže nefunguje na nich žiadna hra, ktorá testuje polohu lúča cez IN #FF.

Riešenie je jednoduché - pomocou 470R odporu sa spojí D7 z VRAM s D7 z hornej RAM. Odpor môže byť aj väčší, malo by chodiť čokoľvek až do cca 1k5. Menší ako 470R neodporúčam.
