Back in the day I used to convert Game Gear ROM's to SMS ROM's to play in my emulator on DC using gg2SMS app and it worked great. My question is do you think thes would work on my Everdrive? It is the newer standard variant with the hardware for region bypassing. The new eludes me at the moment. Anyhow I have some GG proto's but no GG, I did have a friend dump them for me a few years back and would love to play them. Now why don't i jsut try and see you ask? Because I am at work and can't do so ATM and I thought this would be the place to ask if it was even worth me trying as this is a very educated board and where better to ask then the official forums. So what do you think? Here is a link of the app I am thinking of using as GG games are just Mater System ROM's for the most part right? I mean I know I did have an adapter back in the day that was large and obtrusive but allowed me to play my SMS carts when my mom wouldn't let me on the TV back then. http://disgruntleddesigner.com/chrisc/segahacking/gg2sms.html If not do you think this is something that could be added as support? I kno Krizz might not want to as it may hinder the sales of the GG Everdrive but those are so bulky and the caps leak leaving you with horrid audio if any at all. Besides I like to play on my HDTV using my xRGB2 as it looks better, easier to hold a pad over a GG, and most of all I don't have a GG or flash cart for that matter for one.
i think the reason the gg2sms conversion works while playing on a dc is because the dc can actually handle the game gear images. unfortunatly from what i've heard the same cant be said about the sms. there are some games which run in sms mode but then you have the problem with how to press start on games which require the game gear start button. also after searchibng around it seems there has been a few gg games hacked so as the master system can display them properly but not many. tbh i play game gear using the sms emulator by xport for xbox. seems the best way atm unless you get a game gear and game gear everdrive but the game gear itself has a lot of issues
I had a device that allowed me to plug my SMS cart into it and play them just fine. There is one for sale with a busted GameGear here. I would get it but I already have five ED's waiting for the NES. Then to replace my Everdrive MD with the Mega ED so I only need one cart as I hate switching to my backup cart for my many sessions of Vay and Lunar on the Sega CD. The built in save feature with the cart sold me but I waited out for the Mega Key hardware version of the first Everdrive MD so I am not looking to replace it so soon. Guess I will have to try this myself and report back when I can find time after the holiday weekend. Till then I will check back to see if anyone had any luck using the gg2sms app and their Everdrive's
Huh? I don't see a gg2sms app there. Those games were specially reprogrammed from GG format to SMS. Castle of Illusion worked on SMS unchanged because it's barely a GG game at all. Doing that isn't quite useless though, the game's Japan version wasn't on an SMS cart.
yeah, what gg2sms app are you referring to atreyu, or were you just referring to that guys conversions in general?
there was a game gear to megadrive/genesis app called gg2md aswell. don't think it worked very well tbh
GG2MD is meant for Genesis emulators, which is why it would work on the DC, because it's an emulator. The EverDrive is not an emulator. I believe the few GG roms which Chris Covell converted for SMS will work. That tool converts the header to SMD (Super Magic Drive) format, an old copier format.
S Shoot thought the link was on there. I have it on my hdd somewhere I got from zophar sometime ago. I will find it when I get home hopefully this evening.
What this gg2md tool did was only to add an appropriate header to the ROM so that it can be used with a Magic Drive. Supposely, the Magic Drive will put itself and the console in SMS compatibility mode (simply done by driving an input signal on the cartridge port, just like what PBC does). The patched rom won't work on anything else than Magic Drive, it´s not even meant for emulators and this won't work anyway properly with game gear games because of the differences between MS and GG hardware listed on Chris Covell website (color palette and start button issues). Similarely, there is no way to automatically convert a game gear ROM to a master system one and there is no gg2ms "tool", all those games on Chris Covell website were hacked manually and separately. It's more like porting except you are only dealing with a few hardware differences which require some ROM patching, when it is possible off course...
it was a while back when i tested the gg2md tool and yeah i had limited success with some game gear games on my super magic drive plus copier. was horrible if i remember right.
actually, result is exactly the same if you rename a gg ROM to .sms and load it in an emulator or the MD and MS Everdrive: START button does not work and color palette will be wrong because Game Gear use 12-bit color pixels while Master System or Mega Drive in MS compatibility mode is 6-bit (even Mega Drive is only 9-bit) This is hardware limitation that cannot be fixed hence why the only way to get GG games somehow working is to manually hack the ROM so that color RAM writes are converted to 6-bit format and START buttons reads remapped to an existing button combo or into PAUSE button interrupt handler. There is also the problem that GG games assume a 160x144 pixels screen area so even if you will be able to see more on a TV screen (256x192), the outside area was not supposed to be visible so sprites are generally not able to move into there and it might display garbage, depending on how the game was programmed.
