Saturn: Virus game 3rd disk is missing

[Roman Samokha]

A Virus, the game.

First of all, sorry for my probably horrible english, i'm not american or from England.

The problem is, when i downloaded all three disks and completed two of them, i found, that the third disk is actually second. Well, you know, 2nd and 3rd disks are the same, and there is no 3rd disk at all. Did someone faced the same problem or can help me something? I did not found any related topic on this forum, probably because nobody gives a crap about this full japanese game, except me. But i decided to try anyway.

I'm using Saturn console, not emulator. If this could help anyhow.

Edit: I found a solution by downloading all-in-one archive (1.4 Gb). But still, just be in case of that problem.

Kind regards,
Roman
