Game fades in seconds after power off, unless you chill it in liquid nitrogen. It is SDRAM inside, needs power and constant refreshing.

Too expensive =P


Cheers mate, thanks for your answers. I'm now 100% sure. I'm gonna get the old version. For all my needs, useful for testing my hack and others, and some classics I used to play. It can do all the stuff I want it, so it's pointless paying an extra £40 - £50 for the better one when the old one can do just what I want =P


EDIT: Retrogate.com was the only one with Everdrive MD for sale. Everywhere was sold out. So I bought it from there, via paypal of course. Anyone used retrogate.com before?

EDIT2: Nevermind, just got told it's Krikzz own site, so I think I'm pretty safe there.

As a tech member, I fear I should know this, but I specialise in 68k asm. So here I go.


My new EverdriveMD came today and will test it tonight once I can get to my parents tools (drill the hole in cartridge, etc). I'm going to try my "Sonic 2 Time Attack" game, but due to the cheats system, when in any level, it does write to the SRAM every single frame. Stupid question, but is this bad for real hardware? It won't stress it at all, right?


I can easily take the cheat system out, it's mainly in place because it's very easy to cheat using emulators and with hardware, it isn't. But thought I'd ask either way.

If the cart uses something like EEPROM instead of battery backed ram, yes, it's a HUUUUUUUUUGE problem. You only get 100,000 or so writes, and you're doing thousands per hour. The EverdriveMD uses FRAM, which is rated for about 1,000,000,000 writes or more, so it's not nearly so bad, but I'd still change that in case someone uses your game on a cart that uses EEPROM.

Cheers. I tried it and it works fine, but I have taken the cheat system out for hardware purposes. Although, I don't want to share that version out, otherwise I'll start seeing a lot of people posting times when cheated =P


Either version works fine, but because of what you mentioned, I will use my new version for hardware only =)

I added a disclaimer on the wiki for those wanting to use the hack on real hardware. If you upload a version of the hack in the future that takes out the cheat system feel free to change the disclaimer on the wiki to mention the cheat system is only in previous versions of the hack.

Thanks, mate. I will come up with a version for hardware in the future. Could put like a watermark in the "your times" menu...

Actually, I'm going off topic here =P

I am thinking about picking up a Mega Everdrive. Are the only compatibility issues with the usual suspects (Virtua Racing, etc)? Also, stupid question, but I will retain the benefit of playing games on hardware as opposed to emulating the game? The part about the emulation allowing for Master System games and possibly other systems threw me off.

[redhotsonic]

All other games I've tried and downloaded work perfectly. As for the Master System, it's instead of putting that "Master System add-on". None of it is emulated, unless I mis-understood your question.

[Friend of Sonic]

That's what I figured, but someone mentioned about emulation for the Master System. Up until I read that, I figured the cart used the hardware like the original ad on did.

The PBC is just a cart adapter - there is no SMS hardware in it at all. The BC hardware is all in the MD itself. All new MD flash carts have the equivalent of PBC built in, allowing the BC of the MD for SMS games to work. The MegaEverdrive has the edge because it also supports the unlicensed Korean game mapper as well as the Sega and Codemasters mappers. Please note that SMS games won't work through the 32X - if you want to play SMS games, you have to remove the 32X. On the Nomad and Model 3, you also need to mod the console to connect the SMS pin from the cart port to the MD ASIC or it won't switch into SMS BC mode.
