What is a large amount of RAM useful for? And by large amount, I mean RAM memories measured in the MBs, starting from 1MB up to the 16 MB of the PlaySoniq…

Let me start by mentioning three uses I know of:

  • VGMPlay — Most VGMs stay well under a megabyte when decompressed, but there’s several which exceed it, especially those which include DAC samples, e.g. several Sega MegaDrive VGMs, or Skate or Die! (before it was optimised with streaming commands which I don’t support yet). VGMPlay used to have an internal limit of 4 MB, but I had to increase it because there were a few VGMs for which it was not enough…
  • RAM-disk — Even to fit just a single floppy disk already consumes close to a megabyte, leaving only relatively few for the application program. I used it recently because I didn’t have a spare primary slot for the MegaFlashROM SCC+…
  • Disk cache — Like DOS2CASH / LUNA, although with today’s fast flash storage it probably does more harm than good…

I’m sure there must be more, just they don’t spring to mind at the moment Smile.

(Inspired by Lynn’s bold statement that after buying an 1MB memory mapper she’d be settled for life ;).)

As soon as I can run the largest thing I want to be able to run I'm happy. I don't need a crate of RAM to run a 2MB ROM anymore because I flash the ROM instead of loading it into RAM. Furthermore I do not know anything that needs gallons of RAM. Everything up to 256kB hungry can run on my 512kB expanded turbo R ST. If I want more (and the program supports it) I plug in an extra MB cartridge. Or when I want to make people laugh I insert Playsoniq for the funky bootscreen's RAM message.
Everything it was good for, RAMwise, is history. I don't need to preload the samplekits of Fuzzy Logic's Muzaxdisks. I almost forgot about Fastcopy since I hardly remember how a disk looks like (lucky me it's a save icon in modern tools). I don't have it anymore, but MCCE made a cache program for the notoriously slow microcabin games. Would've been handy if I still used disks, and I still played games.

Somehow I think in the present time with Nextor and stuff 512kB is about the ideal amount of RAM to have. Not too much, not too little.

Can anybody tell me why Supersoniqs put such a friggin shipload of RAM in Playsoniq? I'm clueless on that one.

You can play large midi files with more ram. The midi-pac midi player supports 4MByte of msxdos ram.

RoboIMF player uses up to 4MByte of ram as well for larger files.

Back in the day I used a 1mb mapper so I could download a 720k floppy in a ramdisk.
And I once made a 1mb version of Metal Gear 2 (for personal use ofcourse Cool ).

Do both MIDI players support external memory as well when used on a turbo R?

GEM, the Gameboy emulator for GFX9000/Powergraph recommends 4MB and supports 8MB max.

Yes, well at least with the MFR. I tried it on my (unexpanded) Turbo R ST holding the 4 key during boot, and for both players the 512k of the memory expansion is used. This way i could play files which otherwise did not fit Smile

Using the Nextor 4-key hack to force the external mapper to be primary does not count tbh, software that can use >192K of memory should just support secondary mappers by themselves, and be able to use the total amount of memory and run on the R800 at full speed… (does RoboIMF? if no, feature request from me Wink)

Btw, that’s quite a bit of software mentioned already. Indeed as Meits said a lot of the stuff that a lot of memory used to be useful for kind of lost its use (cache, cracks, etc.), but new stuff appeared.

I think it is because of cartridges and flashroms (most game are released on cartridges or in rom format) lessened the need for more memory. A bit unfortunate, since I'd like to put my 20MB to good use.
