Stuff to add/fix for the next release of Virtual Jaguar
-------------------------------------------------------
-- Need to propogate blitter fixes in the A1 <- A2 direction to the A1 -> A2
- direction and the GPU fixes to various instructions to the DSP. [Shamus]
+- Fix VC behavior to match what a real Jaguar does. 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]
-- Need to fix PAL mode to work with the virtual screen code. [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. [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.
- [Shamus]
-- Code to stretch the display in a generic way would be nice. [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]
-- 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. [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]
+- 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--nwagenaar]
- Would be nice to have a GUI for things that are set on the command line or
in the config file. [Shamus] [DONE--Shamus]
- DSP code needs to be rewritten. [Shamus] [DONE but still work to be done--Shamus]
