The only games that fail that I'm aware of are unpatched games that don't set the TMSS (old games before SEGA added the "security" regs to the MD) or hacks tested with emulators that have data on odd addresses (which will crash on ANY flash cart). Obviously Virtua Racing doesn't work - no SVP. ;)

The Neo Myth MD 3 in 1 Flash cart is $139.

Note that it comes with a 256Mbit flash cart; that will hold 32MBytes worth of games. If you want to load games from an SD card, you need the Neo2-SD, which adds another $69 to the total.

The Neo2-SD is good for the MD or SNES Myth carts - if you plan to someday get an N64 Myth, you might instead get the Neo2-Pro, which is double the ram and flash of the Neo2-SD; it also costs a little more at $89.

chilly willy, i actually said 32 MEGABITS, i mean just 2 mb of memory to cut down price. or even without that cartridge, i´d pay 150 for it included the sd thingy

Well I wasn't planning to play Virtua Racing anyway.

Can you tell me which of those pre-TMSS games won't boot up?

I want the Neo-Myth for it's extra SMS FM ability.

The size of the cart is pretty well fixed by the availability of NeoFlash GBA flash carts - the entire "Myth" line are just adapters to allow GBA flash carts to be used on other consoles. I think 256Mbits is the smallest NeoFlash GBA flash cart they made.

I do agree that the Myth series should be shipped with a Neo2-SD or Neo2-Pro... at least have that as an available option. It's pretty much needed to make full use of the Myth.

Onslaught
Zany Golf
Budokan
Ishido: The Way of the Stones


All these games have GG codes that allow them to work on newer systems. GG/PAR codes and IPS patch files are supported by the MD Myth menu.

Pfff, I wouldn't play these games anyway.

While the Everdrive is cheaper the FM Syth while not perfect will be better for me. Has anyone have any luck with the Sega CD BIOS changing?

The FM support is really great. It is absolutely amazing to play your favorite SMS games with FM sound! :)

Well yeah, that's the main point of it to begin with. :)

Has anyone have any luck with the Sega CD BIOS changing?

I was able to play a Japanese CD using the patched Japanese CD BIOS using the Neo Myth. I forget which one it was... did you have a particular game in mind? Maybe one of us with a Myth can check it for you.

Well Chilly it was just regular playable japanese games. Like playing Final Fight CD without the shitty English VA, and other things like that. I'm itching for like a Wondermega but someone said the it doesn't work correctly on the X'Eye so I'm being weary on that. Shit I might get a MD2/Mega CD combo or something with Tiido mod the crap out of the MD2 and call it a day.

Well, compatibility comes in stages: first, the CD BIOS looks for the "proper" region info on the CD; this can be patched fairly easily by programs such as ConvSCD. Second, the MD itself has a register that tells the game whether the hardware was set for Japan or elsewhere, and NTSC or PAL; for example, the setting for the US is NTSC elsewhere; a game may check this register and either use a different method of handling the sound and graphics (games that are compatible anywhere - often labeled as World), or simply refuse to run is they don't see the value they are looking for.

While ConvSCD can deal with the first protection, it can't handle the second. A patch specific to the game in question is needed to deal with the second. Using a patched BIOS with the NeoMyth is like using the ConvSCD patch - it deals with the first protection. It cannot deal with the second either. So with the patched BIOS, you might still need a patch specific to a game. For example, let's say a Japanese CD game checks that register for a value showing Japan - while the patched BIOS allows the game to run, once the game runs and checks the register, it then stops and shows an error because you aren't on a Japanese MD.

That's why I asked for specific games, because there's no way to say which games work and which don't without actually trying them.

As to the WonderMega and X'Eye, there's an issue with the RESET line that requires the push button on the Neo Myth be switched to a toggle switch instead. There's a thread on that over at the NeoFlash forums. The CDX works fine (I have one and it's great), so if you have a chance to get one of those instead, you might go that route instead.

I know about that. When I had a region mod Genesis with a Sega CD putting the Genesis in JP mode will give you an error message when booting up the Sega CD.

Eh. Then again I'm going back to Genesis being a cheap ass so I just use the ConvSCD route. I had some Mega CD games and I just already download the ISO and patch it online so for me it makes the Mega CD games useless. :P

The CDX sounds delicious but I heard like some Sega CD games Jurassic Park will not work. I heard Terminator has problems on it as well (and I like Terminator).

How about the sound quality? CCAM possible?

Misunderstanding. They work fine. It was one particular copy of games someone had on one particular CDX - people have had similar trouble with MCD1/MCD2/WM/X'Eye. CDs can get a little picky, depending on the scratches and the exact focus of the pickup in the CD unit.

Given a clean CD and a unit in good shape, all games work fine on the CDX.

The sound on the CDX is excellent through the AV port. The headphone out isn't quite as good (probably used a low-cost, not-low-noise amp in the headphone out circuit).

MMMM. Does anyone else can confirm that Terminator and etc. work on your CDX?

It could be the next system.

I can confirm both Terminator CD and Who Shot Johnny Rock both work fine on my CDX. I don't have Jurassic Park or Radical Rex.

K, thanks Chilly.

Jurassic Park works fine on my CDX.

The NeoMythMenu Deluxe v2.5 is out. This fixes a problem using save ram with SMS games (Phantasy Star); oddly enough, it's been broken for months and no one noticed until recently. :) It also adds the ability to use patches and cheats on SMS games... if you have the V5 hardware.

Thanks for your great work, Chilly. I really appreciate it. :)

@ThunderForce: No, SMS support does not work with the X'eye. It can be fixed though, if I remember correctly.

Hi everyone. I'm wanting to pick up a Neo Myth, but I'm a bit confused. I want to get the most storage possible for my genesis and money isn't really an issue for me. If I get the Neo Myth MD3 in 1 flash cart would I be better served to get the NEO2-sd to go with it? Is the double the Ram and flash of the Neo2-pro usable for genesis? Will loading games from sd give me more storage? I'm thinking of getting an SDXC card for my pandora would that be usable? Basically I'm just trying to find out what to buy to play games on my genesis. Sorry for the dumb questions

Does UMK3 Trilogy work for either this or the Everdrive flash cart?

^No I don't think so. But maybe the next everdrive it will.

Mega Everdrive will support.

So I've gotta buy it again huh?
Bummer.

There is no advantage to using the Neo2-Pro with the MD Myth. The Neo2-SD is fine, and less expensive. SDXC isn't supported right now, mainly because they are too expensive for me to justify buying one to work out the code. :D Just stick to SDHC - they are fully supported and give up to 32 GBytes of storage - WAAAAAAAAAY more than needed.

UMK3 Triology doesn't work on the MD Myth - it's takes a special cart to support that game, which KRIKzz has stated he'll work into his future Mega Everdrive cart. So if you just have to play that game, you'll want to wait for that cart.

Note that right now, ic2005 is selling a bundle with the MD Myth and Neo3-SD. That works for running MD and 32X games from SD, but doesn't allow you to run SMS games. You would need a regular flash cart or the Neo2-SD to run SMS games as well.

Thanks Chilly. Can't wait till it gets here. I never really bothered much with emulation, but there's a bunch of games Ive been wanting to try on real hardware.

The SEGA emulators are good, but there's just something about real hardware. :)

Definitely.

Chilly Willy once said the Tototek Genesis carts have four banks of 32KB save RAM. I could see doing a small batch of homebrew games with them as they also look like a blank cart. Not sure what the Neo Myth can do.

Remember that the save ram is only on odd bytes, so you cannot put code into it. While you can use it for more work ram, data has to be accessed as bytes. Words or longs would need to use the movep commands to be accessed, and therefor not be as fast as the regular work ram.

The PSRAM inside the NeoMyth can be used like regular ram with one caveat - you cannot write both bytes of a word using byte writes. That's because the psram writes both bytes of a word regardless of the individual byte strobes. That means that byte variables in the psram need to be a word in size to avoid problem, or you have to write the bytes using word instructions, specifically dealing with inserting bytes in the word. Makes char arrays a pain...
