  Release Notes
- ----------------------------- -

The game has been ripped and tested on a Jap Dreamcast to be 100% working
according to the walkthru I have.
Echelon has released this game long ago but the release is nuked. Honestly
speaking Echelon has done a good job here when comparing with EG4 although it
is still nuked and I can't find a ppf from them to fix EG4 problems while they
fixed most similar problems here in EG5.

Problems with Echelon release:
1.  Enemies have no AI, You have to tell them what to do.
2.  In scenario 15, you can only find 4 items in the sandfall but you need the
    5th to ride the ballon.

Note: at point 2 you actually can't proceed the game without using a "Cheat"
save file.


  Rip notes (technical)
- ----------------------------- -
*The following notes are a bit technical and is useless to 99% of the users.
*The info is intended for technical users who know what they are doing and if
*they found anything wrong with my procedures, they can correct me or perhaps
*release a ppf.

Capcom have throw in a ton of protections into this game and instead of a few
centralised routines, there are now thousands although they can be fixed by
simple search and replace all:

1. LBA checks
       Easily fixed by using LBA 45000 scheme.

2. Country Check
       Check if IP.BIN (in memory) is "J  " not "JUE".
       I have wrote a small piece of code to run at the beginning of
       1st_read.bin to patch the in memory "JUE" string to "J  " as they are not
       needed after the game booted.

3. GD Tracks Checks
       Check that the LBA of Track 3 is 45000.
       since I used 45000 D/D format, there is no track 3, so I redirected it to
       check track 2. Note that Echelon's 11700 scheme uses only 2 tracks also.

4. GD Size Checks
       Check that that Size of the disk is 0xFFF79E4 (-0861B4)


Credits goes to Echelon for fix 3 and 4 since I learnt from their fixes in
EG4 to EG6.

Echelon has attempted to patch the scen0x.ovl directly. Since these files are
compressed with a variation of LZ77 algorithm, the direct patching creates
mis-fires. It is a miracle that these have not create any problem with EG5
(but it does with EG6). Anyway, I decompress the files, patch points 3 and 4
only since points 1 and 2 are fixed by other means and "recompress" them.

Final Notes:

Like all of my previous releases, the images were created with a variation of
Echelon's method and hex edited directly into Nero format without burning to CDR
first.
