Assassin Special Edition GFX Glitches
Whilst running Assassin in latest beta (15) and 2.8.1 I've noticed these small gfx glitches appearing during gameplay, only happens when the screen scrolls.
Edit: Running the game under my A500+ config the gfx glitch is no longer present. The version I've been playing is the Delirium crack. I've also tried another crack "Assassin - Special Edition (1994)(Team 17)(Disk 1 of 2)[cr]" but there is no mention of the crew that did it, this version also produces the same glitch. So in short, A500 OCS - Glitch present. A500+ ECS - Glitch not present. Last edited by lordofchaos; 14 September 2014 at 15:41. Reason: got the configs mixed up |

It can be normal, OCS-only sprite/bitplane DMA restriction was not emulated until 2.8.0 and this has already "broken" few programs that appeared to work correctly previously.
This game is also relatively new, probably not OCS tested. Need real A500 test, later.. |

A500 tested and confirmed. Identical glitches with 8371 Agnus.

Thanks for confirming, I wasn't sure if it was WinUAE related or the result of it being cracked.

It is game bug but technically it is caused by undocumented hardware bug, HRM describes only ECS behavior (how overscan bitplane dma steals cycles from sprites), even the very first HRM revision for original A1000 hardware.
