Quote: Quoting JackAsserIs GPLv3 compatible with more free licenses or will it taint the whole project? Transwarp is intended to be integrated with cartridges at some point (need to add 2-rev fallback loader for standard format, though). It hooks into the LOAD vector at $0330.
So my stance is that no tainting occurs if your binary uses the KERNAL's LOAD API on Transwarp files while Transwarp happens to be installed.
I.e., if Transwarp is not an integral part of a production and interchangeable with other loaders, a-okay. :)
Quoting JackAsserAnyway, what about a fast saver. I could REALLY use that for EotB. :D Preferably with drum'n'base while saving. Would fit neatly in an RPG setting. ;) Native saver is planned, but i have no idea when it will be done. Submitting the encoder patch to cc1541 repository will happen soonish, though.
Saving will probably be nowhere near as fast as loading, so i guess having the saver be of the arbitrarily interruptible IRQ kind allowing for sprites, music and whatnot would not be a problem. =)
Ahh ok! Good to know! EotB uses $ffd5 (load RAM) but by the looks of it, it's just setting the $c3/$c4 destination pointer and then calls ($0330), so easy to fix regardless. |

It's in the jump table sitting at the end of the address space. |

I'm absolutely floored, congrats on shipping! I remember us chatting about it 10 years ago, it's amazing that you figured everything out. |

Has it been that long ago already? =) But yeah, i've had a draft in some text file for years, and "due to the current situation" (R)(TM) starting around March this year, i decided to type the stuff into an actual assembly source code. Turned out i had to come up with a few more tricks than envisioned initially, but.. yeah. Worked out fine in the end. :) |

Thank you for this incredible feat.
Do you think it can be ported to the VIC-20 ?
Can it be done with the VIAs ? |

Corner case report--
Hardware: Ultimate 64 running firmware v1.28 / 3.7
NTSC mode
Internally emulated 1541
Transwarp Game disk C
With stock ROMs:
Loading Spike behaves as intended.
With JiffyDOS:
When Spike finishes loading and the ding plays, although the speedometer feedback flashes briefly, the screen clears and goes to a READY. prompt top of screen (as though one has hit RS+RESTORE, etc.)
Spike does RUN just fine, however.
I can replicate this behavior on a cold start.
Can provide a documentary video on request. |

Can it be done with the VIAs ? Might be possible. But then it's only sensible for expanded VIC-20, no? The 3.5 KB of the stock machine are filled quite swiftly with Soundemon's loader. =) |

(Additional detail: the load works as intended with Jiffy enabled if I naively use LOAD"*",8 and LOAD"SPIKE",8. The problem only occurs when I use wedge commands.) |

probably best to check first if it does the same on real hardware :) |
