Region Patch doesn't always work

Rather than trying to use a Mega-CD 1 or Mega-CD 2 BIOS on a Multi-Mega/CDX, has anyone tried the other region BIOS, eg:-
CDX BIOS on a Multi-Mega
Multi-Mega BIOS on a CDX
etc
Just thought maybe the Multi-Mega/CDX hardware is slightly different to a Mega CD1/2 so might only load a Multi-Mega/CDX BIOS? :shrug:

 

hi as for it will not work on cdx systems i have tryed i just get a background image
i have not yet try it on my model two

 

I want the Region Patch was applied to Sega CDX v2.21x Bios.

 

OS_V11 FW_V8
Everdrive used Multi-Mega(Asia).
device info => CD-ROM: JAP MEGA-CD

region-free cd-1-u.bin & region-free cd-2-u.bin => ROM-Type:CD-BIOS

Sega CDX v2.21x (1993)(Sega)(US).bin &
Sega Multi-Mega BIOS v2.21x (1993)(Sega)(PAL)(EU).bin => ROM-Type:"SMD"

 

Did you try the bioses hacked by Leonard ?

Thank you. scottzane.

OS_V11 FW_V9
Everdrive used Multi-Mega(Asia).
device info => CD-ROM: JAP MEGA-CD

Sega CDX v2.21x (1993)(Sega)(US).bin => ROM-Type:"SMD" => booting! but BG only.
us_scd1_921011_regionfree.bin => ROM-Type:"CD-BIOS" => BlackOut
us_scd1_921011_regionfree_byteswap.bin => ROM-Type:"UNKNOUN" => BlackOut

 

The byteswap file is meant to be burnt on the 27C1024 EPROM and put on the MD.

US_SCD1 is for the tray model USA unit.

The files are NOT SMD dumps.

They're RAW BINARY headerless files. :-0

So please configure your Everdrive correctly.

Also, the bios modded by me are meant to be used on the MCD unit as ROM chip. I don't know if they require modifications to work on Everdrive.

Ask Krikzz please.

 

I would love to have cdx and multimega true region free bios. If mr. oliveira does this and add jap cd games true compatibility, I will raise him as 16-bit hero in every forum or perhaps the first one do acomplish it.

The Multi Mega / CDX owners would all lift the developer to glory and hail him. Just because Multi Mega / CDX is THE megadrive console to own, that supports everything and can be modded singleswitch to change region for console and 32x aswell and everything. We just miss true region free bios that supports all region games and there is no jap bios availble for these beauties.
