Was VSP and/or AGSP ever used in any commercial games?
I read that the recently released "Scramble 2010" preview was using VSP for the scrolling.
That made me wonder if any of the commercial games back in the day used such techniques?
Considering that it causes crashes on some C64s I think that it wouldn't have made it past QA, but maybe testing wasn't all that thorough back then...

OT, but that got to be the c64scene's answer to "Have you tried turning it off and on again?"... |

yeah. designwise vice sucks at this point like bloody fucking hell. since when do programs change their own options without explicitly asked by the user? |

IT's have been pain in the ass for ages, i wonder why auto tde off-switching wasn't disabled. |

the other emulators donot have any virtual drive crap and just always use "true drive emulation". |

Quote: probably a bit empiric, but sending an UI and then reading error msg
TDE on:
73,cbm dos v2.6 1541,00,00
TDE off and VTD on:
73,virtual drive emulation v2.2,00,00
or
73,vice fs driver v2.0,00,00
(depending if a d64 is mounted or using directly the file system)
TDE off and VTD off:
?device not present
dunno about other emulators =)
The problem is that UI resets the drive and if you access the bus during drive reset a 1541 will lock up the C64.

yes but those other crappy emulators do not support cartridges (so they load super slow), also they only run on windows.
hardly an alternative |

There's an experimental VICE branch that uses virtual DMA to load PRGs, instead of mounting the virtual filesystem:
http://vice-emu.svn.sourceforge.net/viewvc/vice-emu/branches/ch..
This effectively makes it work like starting PRGs over codenet, and it leaves TDE on. Seemed to work fine when I tested it, but I don't know if it'll get into 2.2. I think the main issue is that it'll have to be implemented into each emulator, not just x64.
Maybe someone is motivated enough to register a feature request for DMA based PRG loading that we all can vote for?

you may as well script it to insert PRG as monitor load command OR in fact create whole mem-images prior to x64 launch... |

Actually I'm trying to incorporate my .d64 creator into vice to support .prg's by generating a temporary .d64 with the .prg. But can't get the darn Vice to compile.. bah. |

When VICE autoloads a D64, it turns off TDE as it drags in the first file; surely that's all it needs to do with dragged and dropped PRG files as well, turn off TDE, load the file and switch it back on again (with the option still in place of disabling TDE to use the host machine's file system if anyone is working that way)? |
