Ya but 4 layers may just be a technically possible idea, but not practical. Blu-ray is generally single and double layer and that's likely to be the primary discs we see for along time. Though it would be sweet to have a 100GB recordable disc. Ofcourse anything bigger than 4.7GB would be nice.
From my understanding it is not only possible, but has already been done. I could be wrong, but I'm fairly certain of the matter.
Again, what I meant was that while possible perhaps the process or yeilds aren't cooperative for commercial use.
Atari VCS - no clue Nintendo Famicom / NES - 8mbits. (1mb) PC Engine - no clue Neo Geo - no clue Gameboy - Think it's 8mbits (1mb) for the original, GBC could go as high as 64mbits (8mb). Densha de Go 2 is 64mbits, GTA1 is 32mbits. Megadrive - No clue, but think the largest carts were 32mbits (not counting 32x and MegaCD) Super Famicom - 64mbits, but largest game was 48mbits. However, a hack of Star Ocean is at 96mbits. Atari Jaguar - No Clue Saturn - 650mb/74min CD format (though, thanks to the security ring, I guess you lose some space) Playstation - 650mb/74min CD format. Gamebot Advance - 256mbits Dreamcast - GD-Rom format, stores a little bit over 1gb (wikipedia suggests 1,2gb). The inner circle on the GD-Rom can also store something like 30~50mb, which is readable in a normal CD-rom drive. Playstation 2 - 650mb/74min CD, Single and Dual Layer DVD (4,4gb (4,7gb) 8,5gb) Xbox - Single and Dual layer DVD. Gamecube - 1,5gb "Nintendo Optical Disc" Nintendo DS - currently biggest DS games are 1gbit. Guess the possibilities are there of this system being able to handle bigger carts perfectly fine without doing any magical tricks. XBox 360 - Dual Layer DVD Playstation 3 - single and dual layer BluRay
As far as I know a PlayStation 1/2 CD cannot be larger than 621 MB. The other space is used for aditional information.
the stuff I have read about the Japanese scientist isn´t a dream. They really have made the DVD burning laser , so it can burn more. On a normal dvd if I remember correct then they put the dvd "grooves" closer to eachother. And that is why they got more data on the DVD, and it wasn´t blue ray at all. It is just sad, that I don´t have an English source to it, I read only in Illustrated Science which is a Danish (now very poppy sadly)magazine. But I know they wouldn´t lie about such stuff.
You have to be wary with cartridge based systems - theoritically you can have indefinitely large cartidges even with the smallest address buses thanks to bank switching. So even though Megadrive can address only 4MB of ROM, it is rather easy to make a cartridge that would utilize gigabytes using bankswitching. One example being Super SF II being 5MB.
I think my FFIX disc (one of the 4) is 710mb if you put it in Windows PC. that would be a big ass cartridge! Only if the mainboard can map to anything that big, but then again, why develop a game that takes up that much space? The cartridge would cost over $2,000.
One gig as in one gigabit or 128 mebibytes or the size of two large N64 games. Originally Neo Geo boasted "100 Mega shock", then when that was quickly overcome it jumped to giga. There is no inherent limit to the game size. If you want to know the hardware imposed limit, AFAIK the Neo Geo supports 9.25MiB cartridges: 2 MiB 68K Program 4 MiB Graphics data 3 MiB Sound samples 128 KiB Fixed text layer 128 KiB Z80 Program Also I believe Playstation supports CDs up to 99 minutes.
