I have recenty discovered that the so-called "rram" section used by gint to store its VBR space and a couple memory structures gets overwritten when returning to the main menu. It is thus necessary to get rid of it and store that data somewhere else. My current lead is to have it at the start of the static RAM by querying its address in the TLB. However, the static RAM is very small on SH3 (8k) so the VBR must be made more compact. This change elaborates the event code translation scheme used on SH3 to emulate SH4 event codes. It is now used to translate the event codes to a gint-specific VBR layout that leaves no gaps and thus reduces the size of the VBR space. The gint_inthandler() method has to be modified for every new SH3 interrupt to maintain this scheme. |
