These questions are closely related and have nearly all the same answer. There is a compatibility reference posted on the Sega-Naomi main website located here --->Bios revision and compatibility list<---. This list can be referenced for most of the questions mentioned above. Question: 'Which bios version is better' Answer: No version is 'better' than the other. There is no performance difference between any of the versions. Version upgrades were made by Sega to fix bugs, improve mobo software code, add GD-ROM support. Question: 'Which language...' or 'What language...' Answer: Certain games have slight differences depending on the region they are meant to be played. Some countries prefer 'green blood' as opposed to 'red blood' because of censorship rules. The same thing goes with certain phrases, some things are not allowed to be said (such as profanity/swearing) and are changed per region to be accepted by operators. Most games can be played most regions and 'which version...' would not be an issue. For example, Power Stone is in English when using USA or EXP bios. But if you use the same game with the JPN bios, both text and audio will be in Japanese. Some games only change the game's text. The others show no differences. I would say that 90% of all games will run under EXP bios, so that would be anyones safest bet. Overall, it depends on each person's preference, so others might have a different opinion. Question: 'Where is the bios?' The bios is a large chip located where the game cart is usually loaded as shown here: Which version you have is marked on the white label. Question: 'Where can I get new/different bios?' Look no further than our own AndyGeezer who can offer whichever version you want. _________________ God must love crazy people... ...Because He made so many of them!

On the bios revision and compatibility list Guilty Gear X is marked as USA / JPN only. When tested with a revision D Capcom USA bios the game only worked with "green blood" and there wasn't any option to change it to red blood. _________________ Naomi + Capcom I/O Naomi GD-ROM + Regular Dimm Naomi 2 GD-ROM + Net Dimm 3.17 Sun Eletronics JVS Power Supply Sega JVS to Jamma Converter rev.

With this version, no. If you want English, you need to get the Export version with English "Initial D" words on it.
