I mean that I could expand the RAM of a given MSX 2 to say 4 Mb using an expander like that of Padial. But how much is really needed for most (99.9 %) applications ? :
- Games that run from a cartridge do not need more than the minimum 64 Kb.
- I think that most games based on disk will run with just 128 K or even 64 K.
- MSX-DOS is ok with 128 K (not sure about this).
- Turbo - R games obviously don't run in an MSX 2.
- MSX 2+ are 64 Kb computers, thus games designed for them do not need more than that (besides the fact that they won't run in a MSX-2 !)
That leaves, to my knowledge, only the megarom to disk conversions which used to be very demanding in terms of user RAM. IMHO the nice megaflashrom of Pazos is the best solution to this.
Please correct me if I'm wrong and tell me what is the best option: get an MSX-2 expanded internally to say 256 Kb (512 kb will be very expensive) or buy a big ram expansion cartridge.
