Rewind back in time to NOTAZ’ PicoDrive v1.35b… Now fast forward to DAVEX’s popular “Rewind” mod, which has already been adapted to several emulators, and we’re left with the Unofficial PicoDrive v1.35b R.

PicoDrive mimics the Sega Genesis / Mega Drive and Sega CD consoles.

Unofficial PicoDrive v1.35b R changes:

1. Now you can remap the rewind key (default RTRIGGER).
2. Allows you configure rewind parameters in the new “Rewind” menu, in order to have more rewind time or more smooth rewind.

Quite the update from developer notaz. Reintroducing PicoDrive — the all-retro, all-sega emulator for your PSP.

Notaz’ PSP port originates from Dave’s PicoDrive 0.30 code for the Pocket PC. The Mega / CD emulation is roughly based on tephane Dallongeville’s Gens.

PicoDrive v1.50/1.51 changes:

• Added some basic support for Sega Pico, a MegaDrive-based toy.
• Added proper support for cue/bin images, including cdda playback.
• .cue sheets with iso/cso/mp3/wav files listed in them are now supported too (but 44kHz restriction still applies).
• Added bin_to_cso_mp3 tool, based on Exophase’s bin_to_iso_ogg. The tool can convert .cue/.bin Sega CD images to .cso/.mp3.
• Greatly improved Sega CD load times.
• Changed how scheduling between 68k and z80 is handled. Improves performance for some games. Credits to Lordus for the idea.
• YM2612 state was not 100% saved, this should be better now.
• Improved renderer performance for shadow/highlight mode.
• Added a hack for YM2612 frequency overflow issue (bleep noises in Shaq Fu, Spider-Man – The Animated Series (intro music), etc.). Credits to Nemesis @ spritesmind forum. Works only if sound rate is set to 44kHz.
• Implemented some sprite rendering improvements, as suggested by Exophase. Games with lots of sprites now perform better.
• Added better idle loop detection, based on Lordus’ idea again.
• “accurate timing” option removed, as disabling it no longer improves performance.
• “accurate sprites” was removed too, the new sprite code can properly handle sprite priorities in all cases.
• Timers adjusted again.
• Improved .smd detection code.
• Minor general optimizations and menu improvements.
• Fixed a bug in Sega CD savestate loader, where the game would sometimes crash after load.
• Fixed a crash of games using eeprom (introduced in 1.40b).
• fixed suspend/resume (hopefully for real).
• Improved bin_to_cso_mp3 tool, it should no longer complain about missing lame.exe even if it’s in working dir.
• Fixed a regression from 1.50, which caused slowdowns in Final Fight.
• Fixed some regressions from 1.50 related to sprite limit and palette handling (caused graphical glitches in some games).
• Added ABC turbo actions to key config.
• Some other minor adjustments.

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.
