TBL's EON demo Whdload

This.

Surely it would take less effort to run the demo on higher spec machines, where you don't have to worry about available memory or CPU power.

Of course you could create a floppy (possibly in FFS) containing a single file that is allocated somewhere in memory and then use it as a cache for data retrieval.
But the required machine would no longer have anything to do with a bare A500 512+512, which is the real challenge in competitions and on which we all want these little marvels of code and art to be performed

Try to run HDD with 1.3

My CDTV does this. I have an ECS chipset with 1.3 and a SCSI HD. It's not that hard to run a HD with 1.3, it all boils down to your SCSI interface being supported.

Still lots of work to be done, but runs to completion on my 060 (not so much on plain a1200 and very painful until then).

Expect major gfx glitches (especially for disk 2) and also out of sync music, and various other problems.

Rename the adf files to disk.1 and disk.2 respectively and place them next to the slave.

If anyone wants to lend a hand, I'll share debug notes/disassemblies etc.

What can I say that hasn't been said before... Amazing work Paraj !

i'm afraid i don't understand. is that right?

Looks right, but note that I've only been testing from the command line, so there isn't a proper icon (or installer). Open a shell,cd into that directory and run "whdload tbl-eon.slave nocache" and hopefully it'll work (no guarantees).

awesome thx paraj

Added icon and diskfiles for the less equipped.
Runs to completion on A1200 ACA 1230/28 with a glitch in the parking lot. Otherwise good.

Updated a bit. "Rubber cube" should no longer look like amiga is crashing (it uses OCS "7bpl trick" + copper updates of BPL5DAT, only partially fixed), also now runs code from fast ram. Nearly runs to completion w/o nocache on 060. Still annoying music glitch in late part.

I could test it on a Blizzard 1260 and it ran until the end
here's what I noticed:
- the tbl logo anim at the beginning is sometimes "jumping"
- the demo pauses abruptly at the beginning of the street scene when the car starts to appear, for a couple of seconds
- the rubber cube is glitching indeed
- yeah same music glitch, there is a wrong instrument/music bug for a short time in the room scene
- I couldn't exit the demo as usual like with other whdload demos or games (for me it's configured as F9)
it's so cool to run it on real hardware and CRT, thanks for your work

The rubber cube effect uses the osc/ecs bpldat trick. It's never going to work on an aga machine.

Edit: note to self, make sure you properly read the rest of the thread before replying.

Hi h0ffman, great music for a great demo


Still need to iron out a few things, but demo in itself works fine on fast machines. Main issue seems to be that the loader outpaces the demo[*] - code and data get overwritten before they're done being used. It would probably be all fine if memory allocator was just given larger area (maybe I'll try that a bit later), but I went another route and just delay loading next effect until previous one has finished (which is why there are delays in transitions in the whdload version).



Proper conversion of the "rubber cube" is still evading me. Just using 5-bpl mode (not in any of the so-far released versions) with a bitplane that has bpl5data=$ffff in the cube area makes the colors right, but it still glitches and shadow is missing. More debugging necessary..


[*] Yes I did try lots of different delay things..

it's unacceptable to release a demo today without a hd install version on the side it's 2023 i don't want to hear it

The only unacceptable thing here is the amount of sense of entitlement in your post.

It's an A500 demo which use a non dos format disk.
WHDLoad exists also for this purpose.

Thankfully, I can now sleep better knowing your opinion on the matter...
