N64 emulator for PSP

The most significant new feature is savestate support. You can now save your progress at any point, via the Pause Menu (accessed through hitting the Select button). Savestates are written out to the memory stick, and consume around a megabyte per slot. You can load up a savestate at any time from the Pause Menu, or via the front end (hit the right shoulder button to swap from the rom list to the savestate list.)

 

Other than savestates, the most significant change in R13 is a number of optimisations to the dynarec core which should give a 10-20% speedup depending on the title being played. I've tested these optimisations as much as I can, but if you find that roms which worked with R12 are now broken, try disabling 'dynamic recompilation' and/or 'dynarec stack optimisation' from the rom's preferences screen.

 

I haven't looked at compatibility at all in R13, so it's unlikely that any roms will have started working in R13.

 

I'm interested to hear your feedback on both of these features. Let me know if you have any problems with savestates, or if you've found roms are no longer working in R13. I'll try and keep on top of the comments pages over the next couple of weeks.

 

It's taken a LOT longer to get R13 out than I had hoped. I can't quite believe the last release was in June! I'm hoping now I've got this release out of the door I'll be able to get back to making small, more frequent releases.

drkIIRaziel "saw the light" and decided that if we don't make a release now we may never do, so here it is:

Be aware that this is more like an ALPHA than a BETA (thus the version number) so some things might be broken.

Release thread here

No real changelog, but according to the Readme, a lot of things have been fixed and subsequently broken again. Needs a bunch of other software installed before you can use the emulator, including WinPCap, which is some kind of a network monitoring library/driver.

GBA / DS emulator

03 November 2007 - version 2.5b

 

No$gba v2.5b 3d frameskip, 3d vram viewer, wifi details

 

- nds/3d/debug: vram viewer auto-updates 3d tree view (if any) during emulation

- nds/3d/debug: defaults to disable old/slow 3d debugmsg's (instead vram viewer)

- nds/3d/mtx: removed v2.5 z-rounding trick, allows to change projection per vtx

- nds/3d/mtx: gl_projection set to identity (but max depth +1.0 instead +0.99)

- nds/3d/mtx: all matrix math done by software without using any opengl matrices

- nds/spi: allows to deselect/disable spi bus without clearing the hold-bit

- nds/3d/debug: vram viewer displays texture bitmap for currently selected vtx

- nds/3d/debug: vram viewer draws laser arrow from screen-center to selected vtx

- nds/3d/debug: vram viewer indicates unused lights and color tables by red line

- nds/3d/debug: vram viewer shows color/material/shininess/etc for selected vtx

- nds/wifi/help: added port 24Ch/24Eh/250h, 264h/270h, 2A4h/2C4h, 2C8h/2CCh info

- nds/3d/speedup/frameskip: renders 3d only when needed (capture and video out)

- nds/3d/speedup: position vectors multiply only 3x4 matrix (and add 1x4 * w=1)

- nds/3d/speedup: directional vectors use 3x3 matrix maths (instead slow 4x4)

- nds/key1/help: renamed crypt_up/down (actually encrypt/decrypt) (thanks simon)

- nds/3d/stage2/buf: all 3d rendering/lighting/vtxmaths performed from buffer

- nds/3d/multi: uses a single opengl context shared (and working) for multiplay

- nds/wifi/help: added W_TX_HDR_CNT port 194h bit0,1,2 info (thanks Tim Seidel)

- nds/3d/debug: added new 3d page to vram viewer, treeview for buffered commands

- nds/3d/buf: stores initial frame settings, reallocs larger buffer when needed

- nds/3d/buf: stores commands with original params, and results on each mtx cmd

- nds/3d/buf: buffers all gx commands (for future frameskip and for vram viewer)

- nds/3d/deguglog: appends current matrix_mode as comment to all matrix commands

- nds/3d/softlight: fixed shininess_table index (7bit index = 8bit data div 2)

- nds/wifi/help: renamed W_RXUNITS to W_RXTX_ADDR and moved it to status chapter

- nds/wifi/help: added notes on registers affected by powerforce (and by irq13)

- nds/wifi: reflects powerforce to rf_status (unreported pictochat-lite problem)

- cpu/debug: replaced invalid tmb high-opcode error message by optional warning

- cpu/debug: disassembler shows invalid high-opcodes as such (thanks vladimir)

- cpu: emulates invalid add/mov/cmp thumb high-opcodes-without-high-registers

- joysticks: fixed unstable vint_inputs code (occassionallly skipped joysticks)

- nds/wifi/dslite: debug-iomap recognizes channel-number for type3 RF registers

- nds/wifi/dslite: emulates type3 RF registers (reading, writing, and initial)

- nds/wifi: emulates reading from RF chip, emulates initial power-on RF values

- nds/wifi/help: added RF2958 (aka RF9008) datasheet info (thanks Tim Seidel)

New MAME GP2X 4.9:

 

- The GP2X F200 compatibility has been fixed. It seems to be a bug in the new firmware 4.0.

The 15360 and 33075 Hz sound frequencies don't run (16000 and 32000 Hz frequencies are now used instead).

Thanks to Eclipse for his help testing in the F200.

- The Z80 C core has been replaced by the MAME 0.53 one. It is more accurate and not slower. Thanks to TTYman.
