First, is an implementation of the LSL protected mode instruction. While it's far from perfect (ie: it doesn't check for anything other than a null segment selector), it does help get a little bit further for some FM Towns applications. Second, is a fix for the REP instruction when used with a segment prefix. Essentially, it reverses the use of the segment_override and segment_prefix variables compared to other instructions. This fixes sprite data copied into sprite RAM on the FM Towns version of Raiden Trad. Thanks, Barry Rodewald mailto:bsr@xnet.co.nz |
