note ~0009587 JOTD (developer) 2021-02-17 21:33	68851 ? wow I didn't know some 020 boards had MMU with that chip. Have you tried with "NOMMU" btw?

note ~0009671 FAirlane (reporter) 2021-03-01 19:39	Hi, no, but I tried it now and it did not change anything. All the best Niko

note ~0010153 GalahadFLT (developer) 2021-05-02 11:18	Looks like I have to redo this one for faster processors, sadly I supported lots of versions. Out of interest, which version of SWOS are you playing?

note ~0010154 JOTD (developer) 2021-05-02 11:29 Last edited: 2021-05-02 11:34 View 3 revisions	I think just using fastmem instead of chipmem for program code could fix the issue. I can try that if you want. Your current slave uses 2MB chip file_ok: lea Swos.rel(pc),a0 pos2: lea $100000,a1 bsr _LoadFileDEC lea reloc_size(pc),a0 move.l d0,(a0) lea Swos.prg(pc),a0 pos: lea $180000,a1 bsr _LoadFileDEC ;bsr remove_hogs lea swos_version(pc),a0 this is convenient to debug, but for production you should definitely use expansion mem. Want me to have a look?

note ~0010156 FAirlane (reporter) 2021-05-02 13:22	Most play 96/97. That is the last version of SWOS for Amiga. That is the one I play all the time. I think using fastmem. instead of chipmem. is a great idea. Very nice if you can look at it and just send me beta versions to test if you like to nikosidis(at)gmail.com All the best Niko

note ~0010164 JOTD (developer) 2021-05-02 23:43	ok, here's a alpha version attached. uses only 1MB chip, and 1MB fast. Some graphics are garbled in the menus (chip/fast mixup probably) but the game runs can you check if the speed is better? if it is, I'll keep working on it and the other versions

note ~0010167 FAirlane (reporter) 2021-05-03 09:01	Hi JOTD It did not work good. I renamed to alpha to sensibleworldofsoccer9697.slave This came right away trying to run the game. It flash all the time. Waited over 1 min. without anything happening on screen.

note ~0010172 JOTD (developer) 2021-05-03 19:23	sure it's not just missing PRELOAD tooltype?

note ~0010173 FAirlane (reporter) 2021-05-03 22:13	Hallo JOTD Great news :D The preload was there but I had to press left mouse button when it flashes. I know SWOS 96/97 as for old disk 1 right before asking for disk 2. Maybe that is the reason? Now it is no more slowdowns and I could not see any bug in menu either. Great work :) Thanks.

note ~0010201 JOTD (developer) 2021-05-04 22:45 Last edited: 2021-05-04 22:46 View 3 revisions	excellent! after all those years of complaints, using fastmem fixed it (obviously) but I didn't want to interfere with Galahad excellent work earlier, and didn't really looked into the fastmem support (which wasn't trivial, BTW, there are wrong relocs at the start of the .REL file, I'm glad they were at the start!!). Now I just allowed myself to :) The flash is a debug feature that was left in slave. I'm adapting the 246357 other versions now :)

note ~0010202 FAirlane (reporter) 2021-05-04 23:34	Yes, very nice you found this problem. As noted before I never had the slowdowns on my A1200 Blizzard IV. Maybe the chip RAM access is faster on the A1200?

note ~0010203 JOTD (developer) 2021-05-04 23:53	that may be counter-intuitive but chipmem is slower on accelerator boards, because the board has to access memory through the main board. on a non-expanded amiga, the cpu accesses chipmem in a faster way because there's less interfacing.
