SourMesen 94616b6905 GBA: Fixed sleep mode issues (#214) 
Timers, DMAs and the PPU no longer run during sleep (prevents audio DMA from being triggered and executed), and prevents the PPU from triggering DMAs/IRQs during sleep
This also fixes a bug where the GB-style APU channels could stay disabled permanently after leaving sleep mode (because the StopMode flag wasn't being reset to false)

SourMesen 8a7971397e GBA: Added support for MRC/MCR for CP14 (#196) 2026-07-02 15:54:24 +09:00
SourMesen 4b55c8eab5 GBA: Improved open bus logic (#179) 
-Open bus should update all 32-bits with the OAM value when OAM is read (even if not a 32-bit read) - fixes the DMA_OAM_Bus test
-All writes should update the open bus value (fixes the Unused_location_update_bus test)

+ Refactor layer transform update trigger
 2025-05-10 12:51:58 +09:00
Sour f1256c840d GBA: Fixed regression that caused the test rom to dump the bios to save ram to fail 
This was broken by 32ab5cfa7e
Reading from open bus should probably not affect open bus, since no device is putting any data on the bus in this case
 2025-05-05 21:29:27 +09:00
Sour 4abe8c22a1 GBA: Fixed IRQ timing/regression 
The previous fix for Internal_Cycle_DMA_IRQ was incorrect and broke audio in Mario Golf
This new fix checks the IRQ line after the first cycle of each memory access, rather than at the end of each memory access. This passes all tests and does not require the "delay" that was put in the previous fix, which solves the Mario Golf sound issues

Sour a09708d43f GBA: VRAM read/write stalling fixes/improvements 
-Fixed stalls not being applied to OAM accesses
-Split 32-bit VRAM/palette accesses into 2 16-bit accesses, which can both be stalled separately

 2025-04-28 21:36:00 +09:00
