I honestly don't know if it's a boot or not but the fake YM2151 ain't a very good sign. :wtf:


A couple parties have suggested it's a Korean version, but a couple parties have the opinion it's a boot. Not sure where this will go, but I'd like to get as many folks' thoughts as possible at this point I guess.

Fire Barrell ar ebay - I've been trying to buy this game for almost 20 years (I'd prefer the "Air Assault"-version) but haven't seen it for sale anywhere.

All eproms have blank non-official-looking stickers, no irem seal sticker etc .... there's no way this is not a bootleg ....or?

No original stickers and no heat sink for the power amp, but it has genuine-looking irem/nanao custom chips.
Yet sound chip and dac are not Yamaha original chips. Silkscreen text seems legit, and the original does not have brand names impressed on it either.
It might be a version for the korean market. If it's a boot then it's very nicely made to look like the original. I am not 100% sure.

For reference, the original on system11:

Picked this Metal Slug X NeoGeo MVS Cart recently, so is it orginal or boot?! I wanna say boot :eh: .
Seller says orginal. Came in a blue MVS case with a torn holo sticker, serials scratched off
Theres not many Toshiba branded roms and all the others have the 250 NGH# but no chip manufacturers name, the NGH's do match the master list.
And it doesnt look hand soldered but it may have just been a really good job at it. Like it looks factory other than those roms with no chip manufacturer

AFAIK, blue is the correct color for an original Metal Slug X MVS.
Apart from the scratched serial numbers, everything in your picutres suggests an original cart. Whoever built this cart had access to legit SNK PCBs, toshiba branded ROMs with the right program code (in case you consider toshiba branded stuff as original; personally I don't consider "toshiba branded" as a requirement) and could afford the high volumes required for custom programmed or masked chips with laser marking.
If it's a boot, it's incredibly well made.

Certainly original. The Altera matches. That's unique to this board & was never cloned :)

Wonder Boy PCB, I suspect it's a boot. I need to set Dipswitches to Continue: ON but... no dipswitches?? WTF is this crappy job?

Boot.
If you can't find the dipswitches at the bottom left corner of the board, under the patch board, then some "clever god of electronics" tought of fixing once and for all the problematic loose joints which plagued his game. Needless to say, he didn't need any other settings other than those which maximised his profits. :)
Hopefully he didn't cut of f*** up any trace, in which case it should be an easy fix.

Thanks Asayuki. I've just desoldered the problematic wires, but can't test right now - I'm in the process of making an adapter. But besides the inabity to change dipswitches, this board worked OK.

It's working great now! Continues on ;)
The board has a strange behavior in that, sometimes when turned on, it displays most of the sprites mirrored AND cocktail mode, but just like internet routers, you just turn it off and on again, and its working great :lol:

Anybody with a legit Steep Slope Sliders who can verify if this one's a boot or not? The case label didn't seem odd and the art/manual all looks legit but once I got the bit for opening the cart and saw MX IC's I got suspicious. Also some of the solder joints on IC's 11 and 12 looks shady :problem:

Please click the thumbs for larger photos. Thanks in advance :)

This is Radiant Silvergun, as taken from the interwebz:

Image

The first thing that hits the eye is the custom in the bottom right not being sanded, but rather proudly marked; including a specific sega part number.
The two GALs on the bottom center, replaced on yours with two 74LS373 TTL ics, are also imprinted with a sega part number.
Note also how Sega had branded mask ROMs. On your picture the Macronix 29F16 flash memories are manually numbered with a pencil.
And let's not forget the number of layers!! As the expert eye can see on the original Sega board, the PCB is definitely 4 or more layers. Your cart, on the other hand, has very likely just two. Due to this, the power distribution strategy on the board is entirely different. Finally, the font used on your board to apply the PCB part number is different than the stroke font used for everything else. This might mean that it has been added at the last minute before rendering the gerber files. on Radiant Silvergun instead the same stroke font is used. And by the way, the only sega part number that can be seen around is the PCB model.

Although I don't own any ST-V game, I would still definitely consider the board you posted as a bootleg.

Thank you for yout insights. You're basically confirming my suspicions. What bugs me it the case/label looks legit and the art and manual definitely are legit :problem:

EDIT: if anyone's got a legit SSS cart please post a few photos of the PCB for comparison.

Ok, so I posted about the SSS cart on another forum (for using a PC term :shifty: ) and initially I got the same response but then this was posted by one member:

I personally doubt this is bootleg. I see no way how bootlegers can get this game hacked - such type protection chip decryption alghorythms was RE'd not a long time ago, so I dont know how bootlegers was able to get decrypted data chunks for this game.

I tend to think this is some early game cart, then mask roms was not yet manufactured but developers run out of time, so they reused flash rom boards. have seen the same in the case of many other Sega games.
indeed, scratched chip looks very suspicious, perhaps they want to hide shame fact same security chip(?) was reused in 3 games :)

"regular" rom board is very different, there is Mask ROMs stamped "Sega MPR-something", not Flash ROMs like this one have.


And it makes sense. It's not a high value game. The encryption didn't get RE'd until lately. The cart label I'd say is legit to almost 100% certainty. I'm starting to lean toward it actually being a genuine albeit early version.

I'll be shipping it to someone who will dump it.

Neat find. It pays off going through your games looking for minute details.
