Could TransWarp technically work with C16 or Plus/4? |

Quoting DiggerCould TransWarp technically work with C16 or Plus/4? On 1541, i think it should work*.
On 1551, single-revolution full-density fastloaders have been invented long ago, no?
Would there be interest in a 1541 port for C16?
* You do get the full 1.76 MHz anywhere on screen with display disabled, yeah? I've also just read that you can even get to 2.22 MHz with display disabled. |

A new caveat just rolled in, courtesy of Morphfrog:
If there is a "SYSTEM INCOMPATIBLE" message on install and/or a "?COMPATIBILITY ERROR." (v0.64)/"?COMPAT ERROR." (v0.68) on load, try removing anything connected to the user port. |

Won't get around finishing clean cc1541 Transwarp encoder integration for a while.
For the time being, anyone interested in playing around with it or even releasing something with it can drop me a mail to receive patched cc1541 binary with current transwarp.prg and an example shell script, like the Atlantis dudes did with Lovecats not long ago. =) |

Is there some reason this can't be made into a kernal replacement for easyflash after you make the 30x fallback loader? The code would likely not fit in a KERNAL replacement without a counterpart replacement ROM in the drive itself (at which point there would be some more speed improvement options, but no "stock hardware" feature). And i guess the licenses will clash when basing this on the original KERNAL and drive ROMs. A cartridge fastloader would be the way to go.
Quote:Or make Transwarp Ocean Loader (laugh). You'd load the file it would kick in the fast loader, set up the screen, load the music, start the tune, load the color ram, load the picture, flash the borders while the main crunched proggy loads, then stop the border flashing and wait for you to press space in case you want to listen to more music. :) Keep in mind it's still a fastloader, so screen is disabled while loading. You can fastload a start screen, wait for a key press (while optionally playing music or animation), then fastload the main program, though. The showcase images for the upcoming next release will have at least 2 games demonstrating this kind of multiload. (It's also possible to fastload files from the main program, when leaving the resident code and things like the load vector untouched.) |

Well i'm wondering what an IRQ loader could do. :)
But more useful would be making versions of Lucasfilm stuff that WORK FROM D64.
LOAD":*",8,1
SEARCHING FOR :*
(black screen)
load transwarp.
load Lucasfilm intro, and play it.
load main game.
start.
Requests.
Ballblazer
Koronis Rift NTSC (this might be tricky, dunno if there's enough space to fit transwarp in on the disk)
The Eidolon (with music patch to make it sound like the early version)
Rescue on Fractalus (based off of vorpal version, not off of wacked out Joe Loader version)
the goal is a .d64 version that loads at least as fast as the original disk after it's be parametered, and acts similar to the original. |

You can use Transwarp as a booter for games, which would then proceed using an IRQ loader and continue loading standard-encoding files in the background. |

Then again, in 2021 you can just make an EF version that "loads" even faster :) |

Those games didn't IRQ load to begin with.
first version of rescue on fractalus used a variant of joe loader that used a different directory track and that sd2iec doesn't recognize. there are cracks of it that works with standard joe loader, but they do not load and save high score properly.
But the real point of this tool is to make d64s that work on a stock 1541 and c64, and load super fast.
Vorpal itself is 10 blocks (VLOADER from the vorpal utility kit), and itself fastloaded with a 1 block autoboot (VBOOT from that same disk).
I see the demo disks cheat and shove 19 or so blocks of transwarp into the directory track, making the loader effectively only take 13 blocks. This would make it difficult to adapt to games that use a lot of files after the main load instead of a track and sector loader.
Installing transwarp to the directory track is not really a solution for the cart. but it needs to have the ability to install transwarp to the disk. Also a way to install a transwarp with a MENU, or to just link it into the first file the way the demo disks do it.
How many blocks (before encoding) can transwarp currently load? |
