Deluxe Pac Man - getting stuck in a wall/loss of control
Hi there!
I hope you can help me with my little problem, to be quite honest I'm totally at a loss why this game behaves so strangely: it loads fine and at first it plays allright too but after some time (usually after a minute or so, sometimes sooner sometimes later) the player sprite suddenly kind of "de-rails" and ends up in a wall, firmly stuck. Like this: ![]() I tested multiple versions/cracks (both AGA and ECS) and all of them behave the same - even the official full versions approved by the author that I downloaded from Amigafuture.de. ![]() So I guess there must be something wrong with my emulator settings. I'm using winuae 1.6.1 and the appropriate kickroms together with the GameBaseAmiga-frontend which uses the following "gemus value pairs": AGA Version: kickstart_rom=v3.1 A1200 nr_floppies=1 floppy0type=0 floppy1type=-1 floppy2type=-1 floppy3type=-1 immediate_blits=true ntsc=false chipset=AGA collision_level=playfields fastmem_size=4 bogomem_size=0 chipmem_size=4 cpu_speed=max finegrain_cpu_speed=max cpu_type=68020 cpu_compatible=false cpu_cycle_exact=false blitter_cycle_exact=false statefile=savestates\Deluxe Pacman (AGA).uss ECS Version kickstart_rom=v2.05 nr_floppies=1 floppy0type=0 floppy1type=-1 floppy2type=-1 floppy3type=-1 immediate_blits=false ntsc=false chipset=ECS collision_level=playfields fastmem_size=0 bogomem_size=0 chipmem_size=2 cpu_speed=real cpu_type=68000 cpu_compatible=false cpu_cycle_exact=false blitter_cycle_exact=false statefile=savestates\Deluxe Pacman.uss Any ideas what could be the cause of this bug or are more details required? Thanks in advance for your suggestions! ![]() |

I'm not sure, but maybe try cpu_cycle_exact=true

No luck...this produced all kinds of weird graphical glitches and ultimately a crash in both versions.
![]() But thanks anyway. |

Ever tried the ECS version with the most common A500 quickstart? I would use KS 1.3 instead of 2.05.

The most of Belgarath's GBA configs makes sense. IIRC the ECS version needs a 2.X kickstart. I tried both versions via GBA, no problems here.

Using Kickstart 1.3 produced an "assign failed returncode 20"

Okay, I'm using the 1.2 version here and it works fine with the quickstart. Seems like Belgarath included a later version that requires KS 2+.

You're sure the "stuck in a wall" bug doesn't come up? As I stated above it tends to pop up after some minutes, usually before you finish the first level.
But maybe all the versions I tested are indeed buggy. So, could someone please upload his versions to the zone? Or is there anything else I might have overseen? |

Played till level 3 without any problems.
Have a look on the EAB file sever (http://eab.abime.net/showthread.php?t=43633) in the folder 'TOSEC/Games/Public Domain/[ADF]'. Try one of the 1.2 versions. |

GBA versions are in the Zone.
![]() btw: you can edit the "GameBase Amiga.uae" in the Gamebase folder, if you want to tinker with some settings. I've never seen this "stuck in the wall" bug. Sorry. |

Nope, those versions are the same I tested this afternoon, with various settings...to no avail.
![]() Are there any rules of thumb for what could be the most probable culprit for such a kind of bug? As a novice I feel like searching for a needle in a haystack. |

Hard to tell, at least we use the same game/emulator versions/WinUAE configs. I can't reproduce your bug at the moment.

It may matter a fraction of an inch whether the bug does show or does not show. Quote:
The 'assign' (et. al.) commands used on the disk were taken from WB 2.04 or higher. And that's why they spit out a "return code 20" if any Kickstart less than 2.04 is used. I agree it may be hackery but I've often managed to replace these kinds of commands with 1.3 ones and the game ran just fine on my then-OS1.3-A500 ![]() Last edited by andreas; 29 June 2009 at 19:43. |

Do you use keyboard in joystick emulation mode? Perhaps game gets confused when pressing both left or right and/or top and bottom direction simultaneously. Which is obviously impossible if you use normal joystick

Well, even though this means I won't be able to play this game with keys at least now I know nothing's wrong with my configuration. ![]() And while your here Toni, THANKS A LOT to you and the rest of the uae-developers for your fantastic work on the emulator and to everybody else for their suggestions. ![]() Cheers!

Careful, Toni... You don't want to encourage attempts to break it again with vague bug reports.
