Summary

0005776: Brian the Lion (AGA) crash

Description

Start Brian the Lion - AGA version
Completing the level "Spooky Ruins" with remaining time (Bonus Stage) will result in a crash:
Exception "Line 1111 Emulator" ($2C) at $C41A6 occured.

This problem does not happen with the OCS version.

Steps To Reproduce

Start Brian the Lion - AGA version
enter code: 93/a/MZXY3
go to far right "Spooky Ruins" (last blue point on the right)

Speed run the level to complete with remaining time and reach "Bonus Stage"
You can also use infinite energy trainer to do this.

This possibly happens in other locations too..

Additional Information

Tested both WHDload slave 1.4 and 2.0
Tested A4000 68040 and A1200 68020
Tested with Fastmem Zorro2 and Zorro3 4MB and 8MB
Tested A1200 kickstarts, 3.9 and 40068 and kick39106

Setting a breakpoint in WinUAE debugger on $C41A6 will show the illegal instruction.

Notes
note ~0011725 ztronzo (reporter) 2022-08-24 20:31	When I added 4 MB of Chip RAM (instead of 2MB and no FAST RAM) it worked fine

note ~0011726 ztronzo (reporter) 2022-08-24 20:41	to elaborate, although the readme requirements say 2.0 MB ChipMem and 3.5 MB OtherMem for AGA version. Works with: 4MB Chip RAM and 0 MB Fast RAM Crashes with: 2MB Chip RAM and 4MB Fast RAM

note ~0011727 ztronzo (reporter) 2022-08-24 20:48	And magically there is no illegal instruction after at the same location 001546B8 49f9 0018 a8d2 LEA.L $0018a8d2,A4 001546BE 4eb9 000c 41a4 JSR $000c41a4 000C41A4 4df9 00df f000 LEA.L $00dff000,A6 000C41AA 41fa 096e LEA.L (PC,$096e) == $000c4b1a,A0 000C41AE 43fa 0cf4 LEA.L (PC,$0cf4) == $000c4ea4,A1 000C41B2 2009 MOVE.L A1,D0 000C41B4 7e04 MOVE.L #$04,D7

note ~0011728 ztronzo (reporter) 2022-08-24 21:31	Conclusion: I believe the game cannot afford losing any of the 2MB Chip RAM. Having multiple Floppy Drives or Hard Drives can cause this problem as they use up a few kb of Chip RAM during mount.

note ~0013972 Velociraptor5 (reporter) 2024-09-22 14:53	Recently, I just for fun tested this issue and have to confirm it. The game really crashes with "Exception "Line 1111 Emulator" ($2C) at $C41A6 occured." Tested in WinUAE 68020/2MB chip/128MB fast, twice (Full Cycle Exact and also in JIT), and the issue is independent of WinUAE compatibility settings. This game is just unplayable, this slave is wrong and should be repaired. Whdl_register is attached. P.S. ztronzo's level code "93/a/MZXY3" somehow doesn't work at me, I had to use code from Hall of Light "sXr7vgqaGP".

note ~0014223 ztronzo (reporter) 2024-11-24 12:40	BTW, I wouldn't say the slave is wrong, as this happens with the original game too when you do an HDD install using the developer's method. But I do wish for a fix. The game demands the maximum Chip memory which is 2MB on any real Amiga, and that's why clicking the workbench icon also triggers a reboot to launch the game. Having anything that reduces the chip memory (such as additional drives or so) will cause the same effect.
