Unofficial PicoDrive 1.35b R (Rewind Mod)

This is a mod of PicoDrive, a Megadrive, Genesis, Sega CD, Mega CD, 32X emulator with rewind support.

Installation

Copy the whole PicoDrive directory to /PSP/GAME/ directory in your Memory Stick.

For games create a ROMS subdirectory and put the roms inside (CUE, BIN).

In order to play any Sega/Mega CD games, you will also need BIOS files. These files must be copied to the CFG directory, named as follows.

• US - us_scd1_9210.bin, us_scd2_9306.bin, SegaCDBIOS9303.bin
• EU - eu_mcd1_9210.bin, eu_mcd2_9303.bin, eu_mcd2_9306.bin
• JP - jp_mcd1_9112.bin, jp_mcd1_9111.bin

These files can also be zipped.

Note that this emulator may require some tweaking of configuration settings to run some games well.

User guide

Supported file types

The game must be dumped to ISO+MP3, CUE+CSO+MP3 or CUE+BIN format. When using CUE+BIN, you must load CUE file from the menu, or else the emulator will not find audio tracks.

CUE+BIN can take a lot of space, so it can be converted to CUE+CSO+MP3 by using bin_to_cso_mp3 tool.

ISO+MP3 files can be named similarly as for other emulators. Examples are as follows (you can name them either way).

SonicCD.iso (data track)
SonicCD_02.mp3 (audio track 1 (CD track 2))
SonicCD_03.mp3

Sonic the Hedgehog CD (US) - Track 01.iso
Sonic the Hedgehog CD (US) - Track 02.mp3
Sonic the Hedgehog CD (US) - Track 03.mp3

In case there is a CUE file with properly specified files names in it, file naming doesn't matter. Just be sure to load CUE from the menu.

It is very important to have the MP3s encoded at 44kHz sample rate and they must be stereo, or else they will play too fast/slow or won't play at all. Be sure not to use anything but classic MP3 format (don't use things like mp3pro).

ISO files can also be CSO compressed or zipped (but not MP3 files, as they are already compressed). CSO will cause slightly longer loading times, and is not very good for FMV games. Zipping ISOs is not recommended, as it will cause very long (several minute) loading times, and make some games unplayable. File naming is similar as with uncompressed ISOs.

SonicCD.cso (data track)
SonicCD_02.mp3 (audio track 1 (CD track 2))
SonicCD_03.mp3

Cheat support (PAT)

To use GG/patch codes, type them into your favorite text editor, one per line. Comments may follow code after a whitespace. Only GameGenie and Genecyst patch formats are supported.

Genecyst patch example (for Sonic).

00334A:0005 Start with five lives
012D24:0001 Keep invincibility until end of stage
009C76:5478 each ring worth 2
009C76:5678 each ring worth 3

Game Genie patch example (for Sonic 2).

ACLA-ATD4 Hidden palace instead of death egg in level select

Both GG and patch codes can be mixed in one file. When the file is ready, name it just like your rom file, but with additional .pat extension. Here are some examples, making sure that case matches.

ROM: Sonic.zip
PATCH FILE: Sonic.zip.pat

ROM: Sonic 2.bin
PATCH FILE: Sonic 2.bin.pat

Put the file into your ROMs directory. Then load the PAT file as you would a rom. Then Cheat Menu Option should appear in main menu.
