Xak 1 WOOMB version loading issues

[sdsnatcher73]

I have been enjoying playing Xak 1 through the RookieDrive FDD ROM 2.0 ;) The version I am playing is the WOOMB translation with some fixes from TNI to run on real hardware.

This game seems to have some issues with this setup (also the original game has issues I will report in a different issue if needed).

Overall the game (images attached) runs fine on my FS-A1ST, however I noticed 4 issues during the game. To reproduce I've created a user disk image (XAK1.FDU in the zip). In general the steps to get to the issues 1 and 2 are:

1. Boot the game from XAK1.FD1
2. Select CONTINUE
3. Insert XAK1.FD2 (by pressing 2, somehow pressing space is not needed)
4. Select 1 or 2 depending on the issue
5. Insert XAK1.FDU (by pressing 4 and space)
6. Insert XAK1FD2 or XAK1.FD3 depending on save 1 or 2.

For Issue 1:

1. After loading the save 1, continue up through the doorway.
2. Insert XAK1.FD1.
3. The game locks up.
   On the same hardware with images written to disk or on openMSX with FS-A1ST with the same images the intermediate demo is loaded and then the game continues.

For issue 2:

1. After loading the save 2, continue up the stairs.
2. Walk towards the cloaked man (Necromancer) and talk to him.
3. After the talk proceed to walk towards Necromancer.
4. The game loads some more data and continue the dialogue.
5. The game screen gets corrupted and the game is no longer playable.
   On the same hardware with images written to disk or on openMSX with FS-A1ST with the same images the fight starts correctly and the game is still playable.

For issue 3:

1. Boot the game from XAK1.FD1
2. Select START
3. After the MICROCABIN logo the demo starts, press space (sometimes you need several tries).
4. Insert XAK1.FD2 and press space
5. The game locks up loading.
   On the same hardware with images written to disk or on openMSX with FS-A1ST with the same images theloading works and the game starts from the beginning. This issue is actually also reproducable on other versions of this game (Issue 1 and 2 may also be but it is impossible to get to that point because of issue 3).

For issue 4 (on a non turbo R computer, e.g HB-F1XV):

1. Boot the game from XAK1.FD1
2. The game locks up loading.
   On the same hardware with images written to disk the game boots fine.
