Oh, I'm wrong... Nemesis 1 was adapted to disk and not to tape as I though (I've read again Martos' post). |

I can think of specific games on the spectrum platform.I remember you had to pass a level then next level was loaded from cassete.Maybe the same could be done with nemesis.The problem is that since all this megarom games were made with the paging option in mind (switching memory banks of 8kbytes or 16) it may not be possible to have all the needed pages at a time,so when you lose at the end boss the 8kbytes that are needed could be at the start of the rom,so you would have to rewind.
This may be wrong,but cassete for megaroms would be too time consuming.Loading metal gear 2 from tape means loading 512 kbytes from tapes.If 128 kbytes are about 16-18 minutes to be loaded from the tape then 512kbytes means 4x16 miutes which is over 60 minutes so over an hour.A day has 24 hours and in the age of digital media this is not an option.
So the rom option loading from tape is only possible for 32 kbytes of roms.
Regads
Ps  ne question ,how on earth was metal gear 2 cracked?I think martos must have been the one that cracked it for the first time. |

Wrong. Using packing and turboloader you can load 128K ROM in 3 to 6 minutes.
If you don't believe me, ask WYZ or pitpan.

I believe you,i may have been wrong.One question though how long do the tapes last,and what is the maximum storage they have?Disks have a duration after which they start being an unstable media.Do you know about tapes?

'unstable' is implicitly included in the word 'tape'  |

Actually any magnetic media could suffer from that  I wonder if anyone has a 20 year old tape and if the programs are still "bloadable" with the command bload"cas:",r

Another question: how much data can you save in a 60/90/120 min. tape?

easy to compute.... if in 6 min you load for example 32 K, in 60 min you can store 320K

Well i think the reason tapes were succesful in the 80ies was probably the fact that you could easily find them as the music industry used them,so there was no need to invest in the expensive disk drives-(after all you could go to a music store and ask for blank tapes).
However 3.5 floppies can still be found today.
Gosh i imagine how much time one would need to save the data.
I still cannot understand the reason konami used the tape as a storage media for metal gear 1.I mean it would be so easy to make it save to disk.The game was only for msx2.Most (if not all) msx2 machines have and had disk drives.This is really weird for me  |

nikodr,
there exist a lot of diskless MSX2 machines, and is we are talking about ex-USSR, more than 90% of MSX2 machines there were diskless.
Anyway I agree that Konami could use "password save" as an addition to tape saving, just as in MG2:SS
