NeoGensPlusGX Xbox

Emulates - Sega Genesis/Megadrive, 32X, SegaCD/MegaCD, Sega Master System, Game Gear, SG-1000, SC-3000, SF-7000, MK3 Emulator

A XtecuterX73 and Madmab collaboration.

So What Is It?

This is a multicore emulator based off of two emulator cores..

Cores are - Gens (Neogenesis) v25.19b, Genesis Plus GX v1.15b. Genesis Plus GX core is by EkeEke. Initially ported by A600 to SDLx.

Mangled and converted to x-port (Madmab Edition) and DirectX by Madmab and XtecuterX73.

Read the Readme-NeoGenesis.txt for all news regarding the Neogenesis core up to v25.14b. Read the Readme-GenesisPlusGX.txt for all news regarding the Genesis Plus GX core up to v1.07b.

Why Multi-Cores?

Because I can? LOL. Actually Genesis Plus GX is so great that NeoGenesis is almost not even needed. Note I said almost. Unfortunately Genesis Plus GX does not have support for Sega 32x. So I decided to incorporate both into one interface with selectable emulator core. Also Genesis Plus GX does not support "Cue/ISO/MP3" image combos which NeoGenesis does support. So there you have it.

FAQS

Q: Can I use my old Neogenesis saves?

A: Yes. Simply rename your saves directory to "NeoGensPlusGX". Also be sure to rename "NeoGenesis.ini" to "NeoGensPlusGX.ini". You will also need to reconfigure your "saves directory to point to the new location. This can be done from within the emulator "Configuration -> Change Default Directories". Or you could manually edit the ".ini" file with a text editor. You might also have to change other default directories depending if they are not relative to the "D:" directory.

Q: I select a game but it keeps on loading the Neogenesis core!

A: If you elected to keep your original Neogenesis saves directory (See above question). A game with a save configuration will still use Neogenesis as the core. You can change this by pressing X when selecting a game and manually changing the core.

Q: I set the core to Genesis Plus GX for my Sega CD image but it keeps on reverting back to NeoGenesis for the core. Why?

A: Chances are the Sega CD image you are selecting is a "Cue/ISO/MP3" combination which Genesis Plus GX currently does not support. So the interface automatically selects NeoGenesis for your confusion.. uh I mean convenience!

Q: How do I get the Pier Solar CD soundtrack to play?

A: If you want to hear the music tracks for Pier Solar. Rename the FIRST track to match the name of your ROM image. So if your rom is named "Pier Solar.bin" then rename the FIRST track of the cd image to "Pier Solar.iso". This currently only works if both images are on your xbox hard drive.

Q: What do I do about UMKT?

A: The UMKT specific Neogenesis core is still there if you need it. However I would suggest using the Genesis Plus GX core.

Q: Genesis Plus GX is known to be able to play SMS and GG games. Can I play these?

A: Yes but there is minimal madmab edition support ATM until I decide what to do about this. No special controller support yet.
