where the falcon release is

a lot of saves here :

http://www.leehanken.pwp.blueyonder....n/GAME_SAV.ES/

EDIT : the music problem is related to a data cache problem (using 'nocache' is helping but not correcting it).

by using 'snoop' command, i have catched 2 errors, the one about the music, and the other about the crash about the night day cycle.

thanks Denis
i'll try to fix it at end of week (too works now for few days)

[CFou!]

little request:



i need save game files just before all manual protection request...



if you have that can you pos t it in TheZone! (AGA&ECS)?

[CFou!]

trainer update

[CFou!]

just information:

we have looking for problem with DLFRSILVER of crash this evening

after some invertigation i am sure game is in the debug of interpreteur

game debugger displays message but message it's displayed on CLI wondow so it's not visible...

it seems crash is caused by original bug in game code... il will investigate to try to found solution to fix it but it"s difficult without sourcecode

[CFou!]

for more information:
after crash game display in Cli error message (i will try tomorow to read it or to display it leaving whdload)

and program 'T.X' wait that 'any key' are pressed before exit it

try to press a key after crash and you will exit of whdload on access fault in CLI

Access failt is normal!!! because 't.x' is leaved to return to CLI window

here executed part of code after crash:

I'am working to fix crash.

try this quick patch it's skip bugged part of code....

I'll let you test the new slave with savegame file(crash2 by example) and see that happens instead of crash game seems now playable without crash but with surprice effect

seeing that you understand why the game crashed.

I should finish tonight to patch integrated debugger of ISHAR 2 to exit properly in case of crash and display the information returned by the debugger when the game crash in the output window of WHDLoad.

I can already tell you that the debugger displays among others the following message in French:
Erreur type: 15
'No de dessin trop grand'

which can be translated as:
Erreur type: 15
'No drawing too large'

Can you test it and qive me you opinion about that ?

[dlfrsilver]

programming error, or the drawing value is errored.

EDIT : indeed, i was right the problem is in two parts :

1) The cycle night / day was indeed a bug in the main executable, and more over a palette problem (despite the error given)

On this one, you did it well, i'm no more stuck or blocked.

This led me to the second part of the crash, which has still to be patched, and related still to the palette problem.

the eagles, when the palette is the night one, only appears as their mask color (purple). The palette comes back to normal once the cycle 'night' pass at 8 in the mornin' to 'day', the eagle get back their good palette.

You're near the end of the tunnel Bébert

maxi value seems to be 30 ($1E) and it's 31 ($1f) went it's crash, i'll compare this evening when it dont crash (after 8 AM)

have you test patch removing temporary crash?

[dlfrsilver]

yes ! it works 50% rest the other 50%, and so far it's really good !

[CFou!]

little update:
purple salve:
- it'is temporary fix (when bug item are purple but game don't crash)

Debug slave:
- it's debug version here game crash but Silmarils debug message is displayed by Whdload when is exit

[CFou!]

can you test this version?

normaly crash is fixed

[dlfrsilver]

well i guess we have to congrats CFOU for this well ended job. Now we only have to go and finish the game and report if there is any problems later in the game

[Chain]

tried it twice quickly only from save point to protection check, but it didnt crashed! woohoo!

marvelous

[dlfrsilver]

and the patch can be applied on disk, if using the IPF or the ADF of the original uncracked game, you need to modify at adress $77AE 303C000F4EB9 by 3E3C001E60E4

On the heresy/Zunt crack the place where the chain is located is actually $BXXX (use an hex editor on PC) and modify it once, save and recompress (yes it's compressed by imploder!).

All this thanks to CFOU

EDIT : i confirm that i also found the occurence to change on the HZ crack. this game was AGA, but the code in itself has never been made really to run on faster processors like 68020 & 68030. On a basic A1200, you have the same problem as seen on the whdload version, the music/fx tracker is the very same as the A500 one.

EDIT2 : Please find in the zone the HZ crack of Ishar 2 AGA fixed with the patch from CFOU tested it, it works nicely

have you some save games just before each protection test?

i need it to verify protection is goodly removed

[dlfrsilver]

the protection test is actually correctly removed, when you meet the second dead woman in the trees of thorm's island

I have tested it

[CFou!]

[CFou!]

have really no save game before manual protection
