Jario64 Java N64 Emulator

Yet another Java emulator for “windows” saw an update today. Most Java emulators will run on a Mac. I was unable to run Super Mario 64 however, the GUI loaded just fine. This emulator is in the early stages of development but, I like to see more Java emulators. More Java emulators means more universal emulators. Java runs on pretty much every operating system. Apparently this new update adds sound. This emulator MIGHT NOT actually work for your Mac but, you are welcome to try. Mostly I’m posting this so that some one might be inclined to make it work for the Mac.

Yabuse the Sega Saturn Emulator


Yabuse is a Sega Saturn Emulator for the Mac OSX and other various platforms. It was last updated on 05/31/2009. As it is a top search right now, I though I would make a post about it. It runs several games and is still being updated. It’s nice to find Emulators people are actually still working on.

To Download – Use the blue Box File Widget on the right panel.

You can check the Yabuse compatibility list by clicking the link below.

Help me support a good cause!

I’ve added several widgets to the blog now, but there’s one I feel is special. That’s the One Laptop Per Child program. Some kids are less fortunate and don’t have access to a computer. There is now a widget on my blog to help support the cause.

SDL MAME UpdateD on Oct 4th


I’m a little late posting this, by a day or so, but the Mac OSX version of SDL MAME saw an update. Several tweaks in the what’s new txt file. Check out what’s new and download from the link below.


MAMETesters Bugs Fixed
- 03403: [DIP/Input] rollfr_2: Can't init Roll Fruit game. (MetalliC)
- 03458: [Sound] bzone and clones: Broken engine sound (couriersud)

Source Changes
Added genuine sets of Rally-X and New Rally-X [Team Japump!!!]

discrete_sound_r now can inquiry any node: [couriersud]
 - the return type is UINT8, consequently the designer needs to ensure
    that the node delivers adequately scaled data.
 - input nodes allow the input data to be scaled. The return value is
    the node value *after* scaling.

DISCRETE_74LS624 - optimized for some more speed. [Derrick Renaud]

DISCRETE_566 - started making a more accurate simulation based on
testing of a real IC. This makes the rest of Sky Raider sounds work.
[Derrick Renaud]

Completed dump of Gun Survivor 2 cart [Guru]

Hacked in the dsp56156's "Long Interrupts."  Added SUB opcode.
Polygonet Commanders now goes in-game! [Andrew Gardner]

plygonet.c: hooked up 53936 roz layer. [R. Belmont, David Haywood]

Fleshed out SCC68070 definition in m68k core, for CD-i use in MESS

m68k: disassemble PMOVE instruction (move to/from PMMU). [R. Belmont]

exp is slow, but pow is even slower [couriersud]
 - more LS624 optimization, replace pow(10, x) by pow10(x)
 - mixer loop optimizations

Impromved discrete performance for mario: [couriersud]
 - pow to exp : 5%
 - parallel tasks : 45%
 - minor tweaks

M680x0 update: [R. Belmont]
 - Add CPU types 68EC030, 68030, and 68EC040
 - Start of 030/040 PMMU, including stubbed PMOVE

Fixed up RAM bank names to prevent crashes with memdump. Extended
explicit banks to 96. [Aaron Giles]

multfish.c driver fixes and improvements: [MetalliC]
 - Hooked up inputs for Roll Fruit
 - Added hopper emulation, payout now works
 - Added information on how to initialize Roll Fruit
 - Added in missing rom to a few MultiFish sets

DISCRETE_555_MSTABLE - optimized speed and added new operating modes.
[Derrick Renaud]

Fixed ROM name of warpwarp. Also removed 4th program ROM which is not
present on real board. [Team Japump!!!]

Memory references can now explicitly specify logical or physical
access by prepending with an 'l' or 'p'. Logical remains the default.
Example: ppb@1000 = physical program space byte at address $1000.
ldw@2000 = logical data space word at address $2000. Changed cheat
finder to explicitly reference physical memory when writing out new
cheats. [Aaron Giles]

Added simple system for auto-detecting cheat-worthy RAM areas.
[Sandro Ronco]

Added NULL check to prevent MAME from crashing if a new input device
was connected at runtime. [David Haywood]

Expanded PROFILER_USERx to support up to 8 custom profiler areas.
[Christophe Jaillet]

Added more _NAME macros to be consistent with the standard naming
conventions. [Atari Ace]

Shuffled code around to better integrate HazeMD implementation.
[David Haywood, Fabio Priuli]

Sped up mario_custom_run() discrete sound. [Derrick Renaud]

Added discrete sound to Sprint 8. [Derrick Renaud]

Removed capacitor aging code and assumed range input is gnd for all
74LS629. [couriersud]

Omplemented m:n logic for buffered task nodes in discrete sound
 - preparation work so that a task node output buffer may be read by
    more than one following task.
 - target: implementation of task groups: tasks in a task group run
    parallel, task groups serial. The current main task may than just
    be task (in the last task group)

Space Walk - started discrete sounds. [Derrick Renaud]

Added static qualifiers where possible throughout the code.
[Atari Ace]

Discrete task groups [couriersud]
 - DISCRETE_TASK_START now requires a parameter TASK_GROUP (>=0, <=9)
 - Tasks are scheduled in the order of their task group
 - Nodes are automatically buffered between task groups
 - Discrete core determines nodes which need buffering to minimize
    overhead (information in DISCRETE_LOG)
 - A discrete block list now must put each stepped node into a task
    if it uses tasks
 - Drivers not using tasks will get one task allocated automatically
 - Updated drivers accordingly
 - Some more constification

Optimized tab removal in srcclean. [Atari Ace]

Centralized color definitions and made some colors more specific.

Hooked up Polynet Warriors joystick properly. [Andrew Gardner]
