No. ROM and RAM a very, very different at the hardware level. Most RAM is really just a series of capacitors (dynamic ram), whereas ROM consists of transistors (permanent logic states).
(Yes I know I simplified things a little, but the point is that ROM is >not< stored similar to how RAM is stored.)
Wikipedia says:MPEG video is just a standard type that was around since Video Discs. That is like 198? or even 197? In 1992 DVD debuted...
- Laserdiscs and CED videorecords (1970s) use NO MPEG compression of any kind. They are analog like videotape.
- MPEG-1 was released in 1993 (after the neo-geo... which did not include compression algorithms).
- DVD - 1996 release
The point is that because the N64 *does* have MPEG compression whereas the neo-geo does not, the N64 can squeeze 2 CDs worth of video (resident evil 2) into only 64 megabytes of cartridge. That same compression would allow an 89 megabyte neogeo game to only require around 8 megabytes on the N64 (or PS1 or other modern console).

Laserdiscs aren't digital video? I did not know that.
Except those 89 MB Neo-Geo games do not contain any FMV of the sort that could be compressed with MPEG!

Grammatical errors aside, this is untrue. Just look at Double Dragon for the Neo Geo.
I think the answer is GB . . .
They have still pictures and various textures that could be compressed. N64 can do that.... Neogeo lacks the capability.
Laserdiscs == composite format video with 533 "pixels" per scanline == Super VHS quality.
Did you have problems understanding me? Apparently not since you were able to answer. My 1st language isnt english so what exactly did you try to accomplish with your first comment?
I havnt played every Neo Geo game, but i know for sure that it was far from common to use FMV in the games. That 1 out of 200 (or how many NG games that exicst) games got a small clip of FMV isnt impossible, but as said, far from common.

Huh? Nobody said that the Neo Geo was incapable of decompressing still images. Compression and decompression of video is an entirely different matter (and can also produce a far greater reduction in size anyway).

Any system is capable of decompression, but where do you decompress the data stored in ROM? Into RAM, of course! And as we all know, consoles always have little RAM. If the Neo Geo had enough RAM to make decompression of graphics into RAM feasible, the Neo Geo CD wouldn't have dropped animation frames.
No, there is no such limit.
surely MPEG is earlier than 1993, as it's used for CDi
cinepak was a forerunner of MPEG compression, used for Sega CD, Jaguar, Mac etc....so NEO GEO could have used that?
Fair enough, but then the N64 didn't necessarily make regular use of compressed still images either, come to think of it. (Or did it?)

What game is that short for or do you mean GigaByte? :P You cant compare like RE2 size for PSX (maybe around 1GB?) to N64 size. If RE2 for N64 takes up 64MB, then that is what it takes.
Could be earlier, but not on CDi. The first CDi units with MPEG encoders came rather late in 1993.
For what?
I think he probbaly meant Gb, not GB (there's that popping up again). The largest DS games are 1Gbit (or 128MB). There's quite a few DS games that clock in at that size so far. I expect that the games will get even larger before the system dies, too. I wouldn't be at all surprised to see a 512MB DS game eventually.
"Still images" would include textures, so yes the N64 used still image compression quite often.
The compression formats we know of on our computers like MPEG, JPG, MP3, etc. are not the most commonly used ones in video games, by the way, or at least they weren't in the old days, I don't know about modern games so much. Usually, proprietary compression methods were used and games like Resident Evil 2 or Conker (which had music in MP3 format) were more the exception. The compression was also usually handled in software, rather than in hardware on older systems, so to say that the Neo Geo is "incapable" of compression is sort of misleading.
...word is bondage...
No. The MPEG-1 reader was added *later* after the introduction of the new specification. It's a mid-90s addon.
...But then, with just a 12 MHz 68k, wouldn't playback of a compressed video while still maintaining a decent framerate be extremely difficult? I mean, there was brisk business selling PC MPEG decoder chipsets back when multimedia was new, and even the PCs of the time were a lot faster than that.
I'll stop talking now.

Ah ok. Then its Gb indeed, not GB. Small "b" means bit and big "B" means byte, then its important to use the right one if the discussion is both talking about bits and bytes to avoid confusionThe biggest DS game i've seen is Resident Evil. Its like 110MB (MegaBytes) which is close to almost 900Mbit. I dont think i've seen a N64 game that is that big.
Considering that Andrew Davie wrote an FMV playback engine for the 2600, I'd say just about anything is possible.
That's huge. Why so big? The N64 version of RE2 was only 64 megabytes (with 25 megabytes of pre-recorded video). Does the DualScreen version include videos?
