| 1 | Stuff to add/fix for the next release of Virtual Jaguar |
| 2 | ------------------------------------------------------- |
| 3 | |
| 4 | - Fix VC behavior to match what a real Jaguar does. Still not sure just what |
| 5 | the heck is going on there. [Shamus] |
| 6 | - Create an EEPROMs directory (or whatever is in EEPROMPath[]) if it doesn't |
| 7 | already exist. [Shamus] |
| 8 | - It would be nice to have the emulator pick up where you last left off, or at |
| 9 | least give you the option of continuing from your last session. This would |
| 10 | require save states, 'natch. ;-) [Shamus] |
| 11 | - It would be nice to have "save states" for instant save/load capability. |
| 12 | [Shamus] |
| 13 | - Cycle accuracy for GPU/DSP/OP/Blitter. [Shamus] |
| 14 | - Need to propagate blitter fixes in the A1 <- A2 direction to the A1 -> A2 |
| 15 | direction and the GPU fixes to various instructions to the DSP. [Shamus] |
| 16 | - Blitter needs fixing. [Shamus] |
| 17 | - In emulator screenshots. [Shamus] |
| 18 | - Audio/video dumping. [Shamus] |
| 19 | - Need to emulate bus contention. [Shamus] |
| 20 | - Need to fix timing in the OP. As it is now, it gives a false impression of |
| 21 | how much it's capable of. [Shamus] |
| 22 | - Fix coming out of fullscreen on Win32. As of now, it doesn't restore the |
| 23 | window position correctly [CJ] |
| 24 | - Fix the Tripper Getem ROM so that it works. It has some tight coupling |
| 25 | between the M68K and the DSP that causes the DSP to starve itself; fixing |
| 26 | this will probably fix a bunch of other timing related issues as well. |
| 27 | [Shamus] |

| 30 | Stuff that was added/fixed |
| 31 | -------------------------- |
| 32 | |
| 33 | - Controller handling. [Shamus] [DONE--Shamus] |
| 34 | - Full screen option. [Shamus] [DONE--Shamus] |
| 35 | - Command line switches for frontends. [Shamus] [DONE-Shamus] |
| 36 | - Fix DSP code so that it doesn't hang in a spinlock waiting for the sound |
| 37 | buffer to empty. Probably a CS lock contention issue. [Shamus] [DONE-Shamus] |
| 38 | - Need to fix PAL mode to work with the virtual screen code. [DONE--Shamus] |
| 39 | - There are a few ROMs that use some "quasi-illegal" 68K instructions. Need |
| 40 | to patch the 68K core to deal with these in a better way than they are |
| 41 | now. [DONE--Shamus] |
| 42 | NOTE: This behavior was verified on Rayman, the problem was due to attempting |
| 43 | to press both left & right at the same time! |
| 44 | - We need a comprehensive way of determining what gets written where and |
| 45 | by whom (i.e., blitter wrote to range $F03000-$F03230) in order to figure |
| 46 | out the remaining problems with various ROMs. [DONE--Shamus] |
| 47 | - Would also be nice to be able to dynamically change the keybindings for |
| 48 | the various keys on the emulated Jaguar controller while inside the emulator. |
| 49 | [DONE--Shamus] |
| 50 | - Make sure that VJ doesn't crash if the useJaguarBIOS key is set to 1 and the |
| 51 | BIOS file isn't available. [DONE--Shamus] |
| 52 | - There is a bug either with the GPU or the blitter (most likely the latter) |
| 53 | which causes the spinning "A"s in the BIOS startup code to be corrupted |
| 54 | when they are showing their backsides. [Shamus] [DONE--Shamus] |
| 55 | NOTE: This behavior has been verified on a real Jaguar and as such is not |
| 56 | an emulator bug. A Jaguar boot ROM bug, yes, but not ours. ;-) |
| 57 | - Make it possible to completely disable the GUI (using a switch like -nogui |
| 58 | or the like) for people running VJ in a cabinet. [Shamus] [DONE--Shamus] |
| 59 | - Code to stretch the display in a generic way would be nice. [Shamus] |
| 60 | [DONE for OpenGL--nwagenaar] |
| 61 | - Would be nice to have a GUI for things that are set on the command line or |
| 62 | in the config file. [Shamus] [DONE--Shamus] |
| 63 | - DSP code needs to be rewritten. [Shamus] [DONE but still work to be done--Shamus] |
| 64 | - We need to have an external configuration file for remembering a user's |
| 65 | preferences, such as key bindings, etc. [Shamus] [DONE--Shamus] |
| 66 | - We need to come up with a way to fix the aspect ratio for pixel modes that |
| 67 | aren't square (PWIDTH != 4). [Shamus] [DONE for OpenGL--Shamus] |
| 68 | - GUI for ROM selection [Shamus] [DONE--Shamus] |
| 69 | - Need to rewrite the main Jaguar execution loop to increment the VC by one |
| 70 | instead of by two, which is how the real Jaguar works. [Shamus] [DONE--Shamus] |
| 71 | - Sound needs a rewrite. With SDL, this shouldn't be much of a problem. |
| 72 | Of course, whoever does this should realize that the PCM outs are probably |
| 73 | not being used for a majority of the ROMs out there--according to the JTRM, |
| 74 | you're supposed to use the I2S interface to output sound since the PCM outs |
| 75 | aren't even physically hooked up in the console! [Shamus] [DONE--Shamus] |
