Still not sure just what - the heck is going on there. [Shamus] -- Create an EEPROMs directory (or whatever is in EEPROMPath[]) if it doesn't - already exist. [Shamus] -- It would be nice to have the emulator pick up where you last left off, or at - least give you the option of continuing from your last session. This would - require save states, 'natch. ;-) [Shamus] -- It would be nice to have "save states" for instant save/load capability. - [Shamus] -- Cycle accuracy for GPU/DSP/OP/Blitter. [Shamus] -- Need to propagate blitter fixes in the A1 <- A2 direction to the A1 -> A2 - direction and the GPU fixes to various instructions to the DSP. [Shamus] -- Blitter needs fixing. [Shamus] -- In emulator screenshots. [Shamus] -- Audio/video dumping. [Shamus] -- Need to emulate bus contention. [Shamus] -- Need to fix timing in the OP. As it is now, it gives a false impression of - how much it's capable of. [Shamus] -- Fix coming out of fullscreen on Win32. As of now, it doesn't restore the - window position correctly [CJ] -- Fix the Tripper Getem ROM so that it works. It has some tight coupling - between the M68K and the DSP that causes the DSP to starve itself; fixing - this will probably fix a bunch of other timing related issues as well. - [Shamus] - - -Stuff that was added/fixed --------------------------- - -- Controller handling. [Shamus] [DONE--Shamus] -- Full screen option. [Shamus] [DONE--Shamus] -- Command line switches for frontends. [Shamus] [DONE-Shamus] -- Fix DSP code so that it doesn't hang in a spinlock waiting for the sound - buffer to empty. Probably a CS lock contention issue. [Shamus] [DONE-Shamus] -- Need to fix PAL mode to work with the virtual screen code. [DONE--Shamus] -- There are a few ROMs that use some "quasi-illegal" 68K instructions. Need - to patch the 68K core to deal with these in a better way than they are - now. [DONE--Shamus] - NOTE: This behavior was verified on Rayman, the problem was due to attempting - to press both left & right at the same time! -- We need a comprehensive way of determining what gets written where and - by whom (i.e., blitter wrote to range $F03000-$F03230) in order to figure - out the remaining problems with various ROMs. [DONE--Shamus] -- Would also be nice to be able to dynamically change the keybindings for - the various keys on the emulated Jaguar controller while inside the emulator. - [DONE--Shamus] -- Make sure that VJ doesn't crash if the useJaguarBIOS key is set to 1 and the - BIOS file isn't available. [DONE--Shamus] -- There is a bug either with the GPU or the blitter (most likely the latter) - which causes the spinning "A"s in the BIOS startup code to be corrupted - when they are showing their backsides. [Shamus] [DONE--Shamus] - NOTE: This behavior has been verified on a real Jaguar and as such is not - an emulator bug. A Jaguar boot ROM bug, yes, but not ours. ;-) -- Make it possible to completely disable the GUI (using a switch like -nogui - or the like) for people running VJ in a cabinet. [Shamus] [DONE--Shamus] -- Code to stretch the display in a generic way would be nice.

[Shamus] [DONE for OpenGL--Shamus] -- GUI for ROM selection [Shamus] [DONE--Shamus] -- Need to rewrite the main Jaguar execution loop to increment the VC by one - instead of by two, which is how the real Jaguar works.
