Corrections for games
Questa pagina è disponibile anche in ITALIANO
Modifications to the ULA circuitry of the +3 and later +2A (and +2B) Spectrums carried out by Amstrad in 1987 caused incompatibility problems with a wide range of pre-existing games. Here follows a list divided into three parts, which gathers the corrections necessary to their solution.
1. Alternative official versions compatible with the +2A/+3, available from the WOS archive
(*) Geoff Capes Strong Man: the compilation containing the working version is unavailable due to the presence of one single game (out of 100!) which distribution is denied, namely Xcel by Activision. I extracted the game data from the TZX file with Tapir and uploaded them here.
2. Games for which there is an unofficial correction available
(*) BC's Quest For Tires: the correction works with all 128K Spectrums since the game runs natively on the 48K/+ only.
3. Other games
Albatrossity: type USR0 at the +3 BASIC prompt before loading the game in order to enable the 128K features. It will run in 48 BASIC but without sound.
