@akira Chris Blackbourn told me it was down to multiplayer consistency, eg if you've got an A500 networked to an A1200, it'd look different on both screens if you had one playing the ECS game and one playing the AGA one.
@warfalcon You're arguing semantics, and it's exactly how other sources describe some of those games (eg
http://hol.abime.net/739).
@amigajay are you using the Psygore CD32 version of Putty Squad? It's got a lot of CD32 specific features, such as high score saving, a button assigned to inflate, blue button jumping, trainers etc.
