There are slight differences in level layout and item placement.

cool, good to know, I had no idea thought it was the same.

NES Super Mario was way off from the Arcade version... especially the later levels

yeah, I know now :p Got any specifics? You almost have me wanting to fire up SMB and see the "new" levels. I never got very far in the arcade version.

if you want some new Mario Bros. levels, you might want to try the New Mario Bros for the DS. I am hooked on it right now...

As for your question, I got something I'm working on that might answer it...

Stay tuned

Jack Burton:
I'm gonna give Chad the benefit the doubt and ask this:

Even though the ROM data on the cartridges was the same between AES and MVS, were the processors or other parts in the various AES and the MVS versions significantly different?  Kind of like how some Xbox 360 models use a different processor from another, yet they can play the same games and use the same accessories.  

Or maybe a better example would be the Genesis 1, 2, and 3.  I'm pretty sure the Genesis 3 is a completely different board inside than the Genesis 1, but they play the same games and use the same accessories.

Also, the Playstation 2 and Ps2 slim would be a good example of what I'm getting at here.

no, that was his attempt at backpeddling. He implied that the AES carts had chips or other hardware in them that made the AES versions as good as the MVS versions:

--- Quote from: ChadTower on October 29, 2008, 12:44:51 pm ---It wasn't.  The home console didn't have nearly the horsepower of the arcade motherboards... so they implemented the difference on the AES cartridges instead.  That's why AES games back then cost so damn much more than MVS games.  The end game was nearly identical but the hardware was definitely not the same.

The AES (home mobo) and MVS (arcade mobo) had the exact same CPUs a Motorola 68000 or Toshiba TMP68HC000 (exact same processor) , a Zilog Z80, and a Yamaha YM2610 .


The carts were expensive because the manufacturing cost was high, the pinouts were changed because at the time the AES carts were cheaper (not MORE EXPENSIVE Chad) then the MVS carts and SNK didnt want Arcade OPs buying AES carts and putting them in the arcades. You can get a UniBIOS in your MVS mobos and flip the switch for AES mode and play the AES version of the game. 

The XBOX360s have the same processors and internals (HD and DVD drives vary but have the same function), just with a better die process to reduce heat, some have newer and better heatsinks but the basic hardware is the same, Same RISC processors and everything else.

Now for the genesis, despite board changes and board layout changes, again the basic hardware remains the same. Motorolla 68000 and a Zylog Z80 for a sound controller(I only know this because its the same as the Neo Geo , lol) and 2 sound chips the Yamaha YM2612 for FM and the texas instuments SN76489 for a PSG  The only "major difference" between Genesis 1,2,and 3 was the G3 didnt have mode 4 support so you couldnt play master system games with a converter.

some info pulled from:
http://www.genesiscollective.com/faq.php?myfaq=yes&id_cat=3&categories=General+Genesis+Information#16
because quite frankly I have better things to do then memorize all the 16 bit hardware out there :)

without getting into the same thing with the PS2 not matter when it came out or how big it is, they all came with the 64-bit "Emotion Engine" clocked at 294.912 MHz CPU and the "Graphics Synthesizer" clocked at 147 MHz GPU

now for "real hardware" changes some later versions of the PS2 slim had built in ethernet ports and of course had external power supplies and the lack of the HD port but none of that has any effect  on how the system runs the game.

JackTucky:
Please stop proving Chad wrong.  The internet can't handle that. 

brandon:
Why didn't they just make the home Neogeo carts hardcoded to  free play so that any operator that tried to use one couldn't make any money? that seems like a simple enough solution to me ;)
