Very good, great Anima :cheers:
Always 8Mhz playing?

Yes.

The main target is actually an Atari STE running at 8 MHz with 2 MB RAM.

It looks like you made a stock STE swallow a whale of a game, and you got away with it!

I keep watching these YouTube videos, shaking my head, wondering how on earth this is possible.
Incredible, fascinating project. Just shows what the mighty STe could have achieved had it been given a decent chance.
Thankyou so much!

Anima, I wonder if there is anything that would prevent you from doing this back in 90s? (If you had access to ROM files and this fantastic color pallete? :) )
If not, ehat would be greater obstacle back in 90s compare today?

I think it was my lesser system knowledge and mainly the lack of emulators like MAME/Hatari. Also, today it is way easier to develop on modern machines especially considering that the CPU performance and amount of memory isn't an issue anymore. So I would say that an experiment like this would've been almost impossible back in the old days.

Would it be fair to say 2MB was not available to most STe owners in the 90s? I mean it was possible, but most people did not have it.

Though the final product may require only 2MB, the development definitely needs a lot more!

Development would require a Cray computer in 90s :D

Btw we have 4MB in STe in early 90s. We also have 2.5MB in ST in 80s but we use Atari for work.

4mb on professional machines used in companies, indeed. But the home user at this time had 512kb ST computers.

you forgot how expensive was such an amount of ram....

For an Atari Workstation, 4mb of ram costed 1450 GBP (14500 francs back in the day) or 1636 euros as of today.

I am not sure what was the price of memory but we were home users, we lived in SFRJ Yugoslavia and we bought Atari ST in 1986.
My father upgrade to 2.5MB before 1990. He used ST for work (German Protext (not UK!) and STad for engineering; I for writing and some DTP).

Later we bought STe somewhere in 1993. with 4MB of RAM.

Sure, most users even haven't had a HD only for playing purposes. So, in fact, it's not the common system requirement for this project but it shows that it's still possible with the original hardware.

2MB SIMM (for STe) in 1991. cost 120GBP. I just check in ST Format so 2MB was quite affordable at time.

2MB STe cost little more (30GBP) than Amiga 500 (512KB) Batman pack in 1991. !!! :D link
Atari with 4MB RAM, SM124, MagiC! and RAM disk was awesome for work! :)

There are some glitches, could that be blitter issues?
The 030 board is still in development so it could be an issue on hardware side as well.

Wow, interesting results. Thanks for testing.

It's an issue with the Blitter code which certainly has a problem with the MC68030 bus timing. Running the current code on the Atari Falcon 030 shows the same glitches. So at least in this case the hardware seems to be fine.

However, Test1 shouldn't work on a machine with an enabled MMU. Probably this has something to do with the one out of ten running issue!?


Actually I had MMU disabled at that time (MMUDIS pin grounded).
Later I can test with MMU enabled.

I also verified with 68020 in place, it shows the same kind of glitches.

I still don't know the reason for starting 1 out of 10 times.
