I've been hoping for a GameGear Everdrive. Gamegear was my first handheld will have to pull it out and dust it off to try this out.
Any estimate of when these two new everdrives might be available?
sms will be available in next few days, gg will be available somewhere in the middle of this month
Thanks for testing those out, KRIKzz. I'm sold. I will get one, but I may wait to see if there's gonna be another group buy here.
You are incredible Krikzz!! Good work!
Wow! Awesome!! Just ordered the Master-Everdrive. Looking forward to the gamegear one!!!!
Very Nice, I'm very tempted to buy one...
1) is it still possible to solder a pause button, like on MD everdrive ?
2) some korean games use special mapper, it would be nice if you could add support for them some day (info about mappers here, list of games using special mappers here)
3) do you plan to make OS open-source (for MD & SNES as well) ? The way I see it, it could bring other people to improve the interface or customize stuff for their need, with you focusing on more interesting things i.e hardware.

nothing, but it's sometime better not reinventing the wheel, having a code base that we know is working is much more practical than writing everything from scratch, especially if you have to write your own FAT driver, hardware initialization routines, etci dont see whats stopping someone from writing there own OS to flash the rom
This is how he makes his money. This isn't just some fun side project for him. I think its better to leave it closed (at least for now). This is just my opinion of course.

Eke whick pause button you mean? pause button on the system body!
i have not plans to implement korean mapper, but i think that this games can be patched for use sega mapper.
i don't want to share sources. and this have not sence. nobody not want to make own os because:
a) that is hard
b) you easy can demage cart if will do something wrong
c) custom os branch will be unuseful after nex my update because this branch was based on old version
d)md os sharing proof it - nobody not make some own OS for everdrive
but some bad china guys easy can use it for "own" things (:
i will publish docs and samples about sd(spi) and usb usage for homebrew and all

No problem, I fully respect and understand your choice.
Main interest for programming my own OS was to test initial state of the console for education purpose (and emulation accuracy off course), before Everdrive software would interfere. But I guess I could simply code my own binary for that, use OS updater then revert to backup OS when I'm done
OS source (v7 I think) was available on your site and I find it very interesting, it also helped understanding how to program MD software that can make use of Everdrive extra features but since you are gonna release documentation for homebrew anyway, it's fine.
SMS pause button off course, the one that trigger NMI for SMS games through cartridge port, which has been removed from later MD Everdrive boards (but ability to connect a switch separately was kept)... I don't see it on the SMS everdrive but is it still possible to add the switch afterwards ?whick pause button you mean? pause button on the system body!

Great work KRIKzz :-)
Just curious, now that you have "SNES Super Everdrive" and "SMS Master Everdrive" have you considered renaming "SEGA Everdrive-MD" to "SMD Mega Everdrive" or "MD Mega Everdrive" to match?
The Master System Everdrive does not feature a pause button because the pause button is on the actual Master System console itself! The MD Everdrive only needs it on the PCB because the Mega Drive does not have a pause button on the console, instead Sega added the pause button to the 'Power Base Converter' for use when playing Master System games:-

console not it default state on the moment when OS begin loading. all my carts have bootloader, this is not updatable part of cart and this code starts before all. also some sms system have bios, so bios will be started even before bootloader.
about button: as say link83 and as i say before SMS pause button placed on system body, not on cart
So are there plans for another group purchase here, perhaps after the Game Gear Everdrive is ready?
It looks great, can't wait to make a complete review about it.
Thanks KRIKzz! I ordered a Master Everdrive last night. I can't wait to play through Phantasy Star again with the YM music (my SMS has the expansion). Oh yeah! I can play Outrun 3D too, awesome!
