Here’s one you may have possibly forgotten about, or perhaps you’ve never seen before… Step back into the good ol’ SEGA Genesis/CD days with developer Notaz’ PicoDrive version 1.40b.

This release is primarily bug fixes and whatnot; don’t expect any speed increase.

PicoDrive v1.40b changes:

• Fixed sprite masking code. Thanks to Lordus for explaining how it works.
• Added “disable sprite limit” option.
• Added black level adjustment to display options.
• Changed reset to act as ’soft’ reset.
• Added detection for Puggsy (it doesn’t really have sram).
• Some small timing adjustments.
• Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing. No recompiler for PSP version though.
• Changed config file format, files are now human-readable. Game specific configs are now held in single file (but old game config files are still read when new one is missing).
• Fixed a bug where some key combos didn’t work as expected.
• Adjusted fast renderer to work with more games, including VR.
• Fixed a problem where SegaCD RAM cart data was getting lost on reset.
• PicoDrive now comes with a game config file for some games which need special settings, so they should now work out-of-the-box. More games will be added with later updates.

From A to B is the new version of PicoDrive — the dopest SEGA CD / Genesis emulator from developer notaz. Version 1.35b packs plenty of bug fixes and additions.

PicoDrive v1.35b changes:

• mp3 code should no longer fail on 1.5 firmware.
• added gamma adjustment option.
• added .cso ISO format support. Useful for non-FMV games.
• it is now possible to force a region after the ROM is loaded.
• fixed a sram bug in memhandlers (fixes Shining in the Darkness saves).
• fixed another bug in memhandlers, which crashed the emu for some games (like NBA Jam and NHL 9x).
• added suspend/resume handling for Sega CD games.
• some other small tweaks I forgot about.

For all the SEGA Saturn skeptics out there, namely here in the comments — this is for you! Introducing Yabause, an early test version which is developing into a full-fledged SEGA Saturn emulator for the PSP. Yep, it is possible after all.

Installation follows the same steps as any other homebrew app or game. We have a 1.50 kernel compiled version, as well a build for custom firmwares 3.xx. You will however need to obtain the SEGA Saturn BIOS by using those resourceful Googling skills you have. Once found, rename to “saturn.bin” and copy the 512KB BIOS file to your memory stick, under PSP/GAME/yabause or PSP/GAME150/yabause — depending which version you downloaded.

Yabause 0.9.1 fw 1.50
Yabause 0.9.1 cfw 3.xx

Good lookin’ out David Roth

Update: Version 1.35a has been released. The quoted paragraph below details the changes…

Well that test-a-bios-and-you-are-screwed bug was quite a serious one, so I’ve done an update:

fixed a bug which prevented to load any ROMs after testing the BIOS.
fixed incorrect CZ80 memory map setup, which caused Z80 crashes and graphics corruption in EU Mega CD model1 BIOS menus.
added additional “set to 4:3 scaled” display option for convenience.
added an option to disable frame limitter (works only with non-auto frameskip).

Something new to occupy a megabyte or two on your memory stick — PicoDrive! The readme details everything you must know about Notaz’ latest SEGA Genesis / Mega CD emulator. Still requires a bit of work, but works well no less.

This is yet another Megadrive / Genesis emulator for PSP, but with Sega CD / Mega CD support. Although it has been originally written having ARM CPU based devices in mind, it has now been ported to PSP too, by replacing ARM specific parts with portable C code. The base code originates from Dave’s (fdave, finalburn) PicoDrive 0.30 for Pocket PC. The Sega/Mega CD code is roughly based on Stephane Dallongeville’s Gens.

Syn-z, the man behind SEGA Genesis emulation, has released his source code for DGEN 1.70. Shortly thereafter, homebrew developer Takka took the liberty in releasing a Slim compatible version. Say it real fast, SEGA!

Brunni’s MasterBoy, which emulates practically everything but your kitchen sink, has received another update which improves on SGB (Super GameBoy) emulation, fixes the SRAM bug that some most likely experienced, and there are other additions/tweaks making it worthy of an upgrade.

2.02 changes:

• EBOOT now has icon, wallpaper and sound (thanks to Ass-Itch from playeradvance for his nice BG/ICON)
• Corrected the bug of SRAM not saving properly for some people
• Added the last save date next to the save state slot number
• Enhanced SGB emulation (runs a lot faster)
• Corrected the garbage showing in the border of the render.
• Reworked the default palettes to be closer to the GBC ones.
• Augmented the maximum number of files per folder to 1024.
• Note: The bug that some people has, save states not working after saving/loading a few, is still not fixed (I could contact nobody who has this problem for debugging). In between, if you have this problem, use the RAM state and save manually before exiting (or save less often).

To quickly recap, MasterBoy emulates four classic consoles & hand-helds: the SEGA Master System and Game Gear, Nintendo Gameboy, Gameboy Colour, and Super Gameboy.

Brunni has updated MasterBoy to version 2.01. Appropriately titled, MasterBoy emulates the Nintendo Game Boy, Super Game Boy, Game Boy Color, and the SEGA Master System & Game Gear handheld. Not only that, there are many configurable options to further aid in your emulation enjoyment — retrofitting the retro, if you will. See MasterBoy.pdf for complete documentation.

v2.01 changes:

• Finished the english documentation on how to colorize your games!
• This version fixes a bug with sound volume when loading RIN states.
• The file list can now display up to 1024 roms.
• Added a small debug mode for the kernel version (copy the EBOOT from the Kernel mode directory to your MasterBoy directory on the PSP - this version runs significantly slower, so use it only for debugging and colorization). For people who reported me strange problems, press L+R+Triangle in the menu. It will show the available RAM. If you have the problem of save states not working after a while, please tell me how this value evolutes. Also, if this mode is enabled when going to Save states, SRAM, Save now, a message box with some information will appear, if you have the SRAM problem (not saving) please report to me the displayed text.
• Bugfixes

After receiving the go ahead from Mr. Akop; DAVEX returns to the scene applying both his popular rewind and mirror mods to SMS Plus PSP — the SEGA Master System & Game Gear emulator.

A little reiteration…

…With rewind you can warp back in time, within the game, without worrying about saving states. If you made a mistake, you can press “rewind” button and undo it….

…In mirror mode, like it’s name says, all graphics are horizontally inverted. So, if your favorite platform game is played from left to right, this time you can have the choice of playing it from right to left…

I know your fancy must be tickled with the “rewind” feature… So in case you’re a newcomer to the PSP homebrew scene, DAVEX has also put his magical touch on NesterJ — the NES emulator, and RIN — the Gameboy/Gameboy Color emulator.

Update: MasterBoy 2.0a is now available. Not sure what the changes consist of. Just download it, and have fun!

Brunni has released MasterBoy — an emulator consolidating Nintendo Game Boy, Super Game Boy, Game Boy Color, SEGA Master System, *takes a breath* and Game Gear emulation — all in one EBOOT!

MasterBoy incorporates a nifty feature allowing you to colorize old GBC games; see examples in the “Colorpak” directory. There are plenty more options which distinguish this emulator from the rest. It definitely deserves a spot on your memory stick.
