    I am interested in getting an NTSC Sega 32X for usage with my PAL Mega Drive and Mega CD. What I am asking is, do I need to mod the 32X console to get any sort of games to work on the system, or because I have a Mega Everdrive with the ability to adjust the roms for compatibility, that is, NTSC Roms converted for use to a PAL system and vice versa, can I just play the games without any problems from the flash cart. I really need help with this, so if anyone can help me, please reply.:boxing:

    You'll need to set the 32X to 50Hz if you want it to work with your EU Mega Drive. Or you could add a 50/60Hz switch to your Mega Drive so you could play your games in 60Hz which would be better :) But ideally you should modify both systems so you can play all games with 100% compatibility.

    Here is some information on modifying the 32X. Basically you just remove the R42 resistor and solder pin 32 on the IC to the middle of a switch and solder 5V and GND to the other legs.

    "adjust the roms for compatibility"

    This is key, makes it a lot easier to understand. Carts don't change the hardware 50/60hz or English/Japanese.

    That mod works a lot better on a PAL 32X than an NTSC one - the problem is that it doesn't change the colorburst and as a result the composite video signal produced when you set it to the other video mode is a non-standard one - but it just happens that the video format produced by a PAL 32X in NTSC mode is the same as the signal that European multiple-standard VCRs used to produce when you played an NTSC tape in them (AKA "NTSC-4.43") - so most European TV sets can handle it without a problem.

    The situation the other way around is not so happy - you basically end up with a PAL signal (including the PAL phase reversals) but with the NTSC 3.58MHz subcarrier - and in my experience most TVs don't like it very much.

    This only applies to a composite connection - if you use RGB, the encoder is effectively bypassed.

    Ah sorry, I never take into account that there are people who use anything other than RGB. You're right of course! :)
