Further Information

1. The different ways, and different levels of region encoding, on 32X games

As explained as part of the introduction, certain games are region-locked, and in several different ways…:

  • 1st method: simply through the frequency. The game’s protection will only check the Mega Drive’s frequency. If the console’s frequency is different to that of the game, you will obtain an error message along the lines of "Developed for use only with NTSC Genesis systems & NTSC Mega Drive systems." (in the case of an NTSC game). These games have on their headers a flag, either type 5 (NTSC) or A (PAL).
  • 2nd method: the console’s country. The protection will check both the frequency and the language of the console. If the country is different to that of the game, you will obtain an error message along the lines of "Developed for use only with NTSC Mega Drive systems" (for a Japanese game). These games have in their header an indicator as follows: U (USA), E (EUR), J (JAP), JU (JAP + USA), 4 (USA), or 1 (JAP).

...and on different levels:

  • Level 1: low-level protection, the most common for Mega Drive games, consists simply of comparing the flag in the game’s header, the frequency of the console, even the language, it all depends… This protection can be bypassed very easily with a universal adaptor, or a Game Genie, since all you need to do is change the value of the header to make it regionless!
  • Level 2: high-level protection, which is very rare (fewer than 5 games use it on the Mega Drive), which isn’t based on the indicator on the game’s header but on an indicator situated within the games’ code itself…
  • Level 2+: the same thing as for Level 2. Not always based on the indicator in the header of the game, but check anyway to make sure it hasn’t been altered... To put it bluntly, if you only hack the header’s indicator, the game will no longer function at all (not even on the console it was originally supported on!).

Regionless games have in their headers an indicator F or JUE (JAP+USA+EUR), or any other indicator shown above with no level of protection.

2. Points about the region indicator

You will have noticed that there are 2 types of indicators that concern the region of the game (which doesn’t necessarily imply that they have a level of protection):

  • The old type: with the initials of the 3 major zones, which are Japan (J), the USA (U), and Europe (E). From these letters, we are shown that the game can function in several zones (if there is protection, the region is extended), e.g.: JU indicates that the game can work in Japan and in America.
  • The new type: it allows the extension of the zones, with values over 4 bits, which gives a hexadecimal result from 1 to F...

Concretely :

0001 -> 1 = Japan
0010 -> 2 = Unknown (PAL zone)
0100 -> 4 = USA
0101 -> 5 = NTSC (Japon + USA)
1000 -> 8 = Unknown (PAL zone)
1010 -> A = PAL (Europe, Australia...)
1110 -> E = Occident (USA + Europe)
1111 -> F = PAL + NTSC (all zones)

The other combinations are without interest...

A propos de iGREKKESS
Fan de SEGA depuis 1991, après avoir reçu une Master System pour Noël. La découverte de Sonic sur Mega Drive m'a particulièrement marqué, je n'avais jamais rien vu d'aussi classe !
Aussi ai-je naturellement poursuivi sur Mega Drive, puis sur les autres consoles de l'éditeur, sans pour autant me fermer à la concurrence, bien que je ne renie pas mes années "Segamaniaque" ("Nintendo c'est du caca"). Spécialisé dans SEGA au fil des années, j'ai logiquement consacré un espace à celui-ci sur mon premier site, dés mon arrivée sur Internet en 1999...

Black screen! That’s what I tried and the result. It’s too hard for someone who doesn’t know much about information technology to do

1983 : l'année du lancement de la première console SEGA, la SG-1000, et de la création des trois mythiques départements internes AM R&D.
