A test version of FB Alpha with just the Megadrive games enabled. There have been significant improvements to the current released version. The following is a list of the major changes:

• Greatly improved timing
  • Changed the YM2612 to use the 68K for timing since the Z80 can be disabled
  • Properly Supported PAL
  • Updated the reset routine to support switching between PAL and NTSC timings
• Changed to MAME's Z80 core - works much better
• Basic SRAM support
• Added support for most games that require special banking, etc.
• General Tidy-up and fix of many small things
• Tested many games and the vast majority work well

I have reopened the database on my web-page to allow users to update the driver with working status, etc. You need to be registered on the site and logged in. Click here to enter the database. Enter the name of the driver you tested (eg, g_soni) and click Amend. You can see the name of the driver in the game selection dialog. If you can't see it then enable the Use Zipnames option.

Once you have clicked the Amend button, you are presented with a form with the following fields:

• Driver Name (read-only)
• Clone of: this should in most cases be left alone)
• Title: (this should in most cases be left alone)
• Year:
• Manufacturer:
• Number of Players:
• Genre:
• ROM Name: (this should in most cases be left alone)
• ROM Size: (this should in most cases be left alone)
• ROM CRC32: (this should in most cases be left alone)
• Status: (working, not working, gfx/sound problems)
• Init Function: (this should in most cases be left alone)
• Dip Switch Type: (this should in most cases be left alone)
• Notes: (any notes based upon your testing that may help identify problems)

When you have made your changes click Amend.

The Megadrive driver that is used in FBA releases is generated from this database so if you want to see more games added please use this test release and post your findings in the database.
