Quoting Zaphodif you do irq load, you have to use the T/S loader. Why? Should be perfectly possible to replace that loader with a modern IRQ loader that loads plain files via directory - and even can decompress on the fly and come out both faster and smaller in the end. |

AS i said, very little room. the main program takes over damn near every bit of memory after running, with barely enough room for it's own T/S irq loader. it's only from $800 to $d370 or so BEFORE it's started.
Any installed IRQ loader will have to fit in the space the old one was in, because there isn't much more.
honestly would probably be easier to NTSC fix the PAL version to correct the music speed, and drop an IRQ loader into it, because it already uses files, but that's above my pay grade. |

Quoting ZaphodAny installed IRQ loader will have to fit in the space the old one was in, because there isn't much more. Why, of course. =)
A quick peek in the code revealed that enough space should be available when replacing the IRQ loader/saver (which seems to be a variant of the G.I. Joe loader, and is somewhat scattered in memory).
I'd go for the original NTSC release, as the non-IRQ loading European release might have too many changes that may prohibit re-adding IRQ-loading. (Haven't compared the two versions thoroughly, but some parts of the code seem to have been moved around, i.e., the game might have been rebuilt from a modified source for the latter release). |

shows what i get for believing Remember about anything. :) They took one look at it and gave up. "there's no room for a better loader."
After all they were wrong about their claimed bugs in Chiller. I have collected both impossible crosses. only one of them even required using another one as a platform to reach.
I really don't know how to do much more than crack and train somewhat.
i suppose you have a memory map and suggestion on which loader to drop in that has a saver too? as far as I know joe loader only loads, though it would probably work. |

Another IRQ loader would mainly be "better" in that it would load and save plain files via directory, which is preferable for a proper crack. Slightly increased speed would be a plus (the files to load aren't very big, though).
Currently, i don't know of any combined IRQ loader+saver that would be small enough after install, then load and save files via directory (should be perfectly possible to make one, though).
(What does the game need a saver for, actually? Savegames or hi-scores?)
For your purposes, replacing the IRQ loader would/saver probably not be required. Replacing "intro" and main program with somewhat modified Transwarp-encoded versions would suffice, as you have suggested. |

It's for saving progress. Score is whatever you've dismantled, plus 100k for destroying the level 20 base. End trip dismantles everything for a cash in, but doesn't get you the 100k.
I'd make the release if i had the needed tool. as i said, i have a 27 block lucasfilm logo called KORONIS RIFT that when ran shows the logo, then kernal loads COPYRIGHT 1985, which is the slightly compressed main program at 193 blocks.
If I had a better tool, I can probably make a logo intro that decompresses faster. this one takes between 1 and 2 seconds.
I'm also not entirely sure the save is an IRQ saver. which may help some. |

No worries, the encoder will be released soon. I just want to add a few more games with separate intro and main files.
I'd try not to pack the files at all, as decrunching quickly eats up the fastload speed gain. Only pack to get files to below $d000, and then only partial packing (just an upper part of the program), with an RLE packer (G-Packer V1.0 came in handy).
IRQ saver or not doesn't make much of a difference. Fitting the drive-side saving part alone is most of the problem. =) |

okay i'm trying g-packer, and dunno what i'm doign wrong. i have main, which is 206 blocks before the packing (going under i/o). it is properly saved off, because i can monitor load it, put in original disk, g 8f0 and it works.
true drive is on, traps are off, and g-packer hangs up no it, and is unable to save a thing. |

Are you using it in PAL mode? |

no because the game i'm tryin to pack is NTSC.
sigh. that would explain it i guess.
how DO i tell g-packer to only pack enough to get it under 201 blocks? |
