AFAIK:
I mean you could just get a RaspPI, install Retropie and have a perfect Neo Geo emulation with all the games working.
I dont wanna start an argument here but: Why?
Hey, this was by no means an attack or dis aimed at you. I just meant: if you dont care if your game is "original" and "unmodified" where do you draw the line. And how do you argue that line of what is "acceptable". Because if you say you dont care about "modified" or "altered"... how justify NOT using an emulator?
I total agree with this point of view as a collecter.The CRC check failing means it's not an original dump of the ROM (because it's had the protection patched out)
Some people (and yes I put myself in this camp) want 100% original operation, I love my CPS2 multi and play it a lot, but still keep original boards running on batteries for a couple of my favourite games - which was then made a moot point when Darksoft released the key writing firmware
I've also desuicided a few games using batteries to keep them original (2 Captain Commando CPS1, Warriors of Fate CPS1.5, several CPS2 boards)
So for the same reason as that, people want the CRC check to pass for all games on the Neo multi, including those with special protection chips.
It's not going to affect operation and as far as I'm aware much the same as CPS2 the patched version doesn't affect anything in game, but it's not original.
99% of people don't/won't care, but there are those of us that do
Why would anyone pay over £100 for a 20+ year old pcb to play one game?
I except that, cheers. I did look at hooking up a pc via Jamma.Hey, this was by no means an attack or dis aimed at you.

I ask myself that exact question from time to time)
The difference, in short, is its not the same game data.
Cheers, i've learnt about CRC check today.
He absolutely has. But he is also a polarizing character. Lets leave it at that.
I can live with should! ( it's only one game )He absolutely has. But he is also a polarizing character. Lets leave it at that.
1. Its not a matter of having the encrypted romset. For that to run you have to have the decrytion logic emulated in the cart FPGAs. And for that you have to know the original logic. Which for some reason the NeoSD guys do (insiders?) and DS does not (yet)
Those two multicarts are a pretty impressive piece of engineering. There is a lot more to them then just loading up some data from SD card to Flash or RAM. DS can surely tell you more about the FPGAs and all the logic and IC emulation neccessary to get this thing running.
2. That depends what has been changed. If it was just decrypted and the decryption was 100% correct it SHOULD be identical gameplay wise.
3. Long story short: I use it for pretty much nothing. Was just curious when I got my first MVS (1b), de-soldered the bios chip and put a DIP socket in. Then put in the Unibios and well...that was it. Matter of curiosity. Never bothered changing it back is all
Well, CRC is a mathematic wizardry (technically a function); you throw a long sequence of numbers (i.e. a dumped ROM data) at it, it crunches it and it spits out a small number. Now logically two different big sequences of numbers can lead to the same small one (CRC collision), but the algorithm (or function) is well designed so, if you change just a part of the input, you’ll end up with two different CRCs. So, this is good for ensuring data integrity. I.e. you can put a big file on a website and put its CRC on the same page; you download the file, calculate the CRC on your own and if it matches the one on the site you can be assured that nothing went wrong during download. Actually CRC checks are the basis of modern packet based networking and, nowadays, you can have a phone call, watch TV, listen to music or read this post thanks to CRC.
The difference is the MVS is getting the same game data it would have from a real original cart.
Razoola, a Neo Geo scene authority with his own personality (as each and every one of us).
The integrity of game data received by the Neo Geo motherboard.
Semantics… if you mean if you can fetch Neo Geo with wrong game data and passing CRC check, the answer is no. If you mean if you can fetch Neo Geo with CRC correct data (so good data) using a non original cart, well, that’s the whole point of a flash cart.
I honestly don’t know. Once I read that some DS functions typical of Unibios were a work in progress. I don’t know if DS completed them. I don’t even know if DS will implement all Unibios functions (i.e. cheats). One point of Unibios is getting those features on the Neo Geo hardware, so having the ability to use them on original carts.
Not exactly. The UniBIOS' CRC only checks the contents of the P roms, which are the chips that contain the game's main program. Things such as sound code, sound samples, sprites and static layer (M, V, C and S roms, respectively) are not checked, because the BIOS does not have direct access to them. What does the P rom check tells us? it tells us that the game code is 100% the same as the original game. It does not have any hack added. It may have corrupted graphics, or corrupted sound (because those roms are not checked), but the game will behave the same as the original. Hope i explained it in a clear manner
I 50% completely agree with you
hahaha
that's exactly a feature i somehow feel a little uncomfortable, and i don't see me as an extremeist in that sense - is it really still my input that moves the character?
Honestly yes. The whole point is that, most of the real hardware after Atari 2600 has input latency, i.e. Super Mario World on a real SNS on a CRT has 2 frames of input latency. Run-Ahead could have the ability of (inaccurately) reducing the input lag to 1 frame (so -1 respect the real SNES); but if you play on a HDTV which adds 1 frame of latency... do the math… you get the same input latency on EMU+HDTV than on SNES+CRT, and this is a feat you won’t get on SNES+OSSC+HDTV or on my beloved Analogue Super NT + HDTV. Pretty neat!
You can try right now, it's a work in progress, but you can try.
That's fair, you're entitled to play what you want how you want.
Right dude, my bad.
