discovered strange behavior

NfernalNfluence · 22 May 2009, 00:48

toni, problem goes way back, seems also to be game specific!! (shinobi, rolling thunder, ...) i would have said something earlier but knew you'd have a tough time duplicating. every now and then, usually occurs, after cold boot and can be easily fixed with another boot or reset. however, after leaving shinobi demonstration for an hour, i came back to find this strange behavior, once againthat is: bottom half of screen breaks away slightly from top and becomes unstable in a shaking like manner!i could provide screen shots but all you would see is a noticeable line dissecting the screen.

Configuration: 1.3 ROM, OCS, 512 KB Chip + 512 KB Slow RAM (most common)

Best compatibility

Randomly appearing black horizontal line is known issue which unfortunately happens really rarely.

I guess the problem also disappears if you save state, restart emulation and load the state? (makes it practically impossible to debug without wasting hours..)

yes, yes, and yes

Did you find any quick way to duplicate this problem? For example does running in warp mode make it faster? (end+pause)

toni, it just happened again but with strider ii. i booted up rolling thunder several times and just after the 3rd, bug reared itself. in my experience, rolling thunder seems to be most vulnerable, that is affected most frequently.
i used turbo to speed up emulation in the case of rolling thunder. i normally don't use this!

update: got rolling thunder to reproduce bug again and again
