mariuszw Posted October 30, 2018 Author Share Posted October 30, 2018 Congratulations, that is a very nice port indeed! I'm not sure if I found a glitch/bug: I've played not very long, but discovered that in two places, the graphics have clipping/visibility problems. I've checked the C64 version at those places too, but wasn't able to reproduce the faulty visualization. (The C64 version was really a cold shower, the original speed is close to unplayable.) Glitch1.png Glitch2.png Do you plan to release even a bit faster version for 128k machines? (Loop unrolling (like in SCR) for e.g. "sub_4608_loop" or "copy_back_buffer_to_screen" could increase the frame rate further...) It looks you have found a bug I guess it is one of my optimizations which broke it. I'll try to find a reason and fix it eventually. I was focusing on making the game work on 64KB machines, so I didn't consider making 128KB version. Actually, almost everything fitted in 64KB apart from game load/save from C64 which I had to remove due to lack of RAM. I'll consider making a version for 128KB machines. At one point I implemented faster integer division based on https://www.microsoft.com/en-us/research/publication/software-integer-division/, but I had to remove it as it is based on multiplying by inverse and it required a table with inverse numbers. I didn't have memory for this table. The slowest part seems to be geometry transformations, and this is difficult to follow and understand in 6502 assembly Mariusz. 2 Quote Link to comment Share on other sites More sharing options...
zeropolis79 Posted October 30, 2018 Share Posted October 30, 2018 Thanks for all positive comments! I really enjoyed it even though I could never get far in it back in the day on the Amstrad.. Hope you liked my video. 1 Quote Link to comment Share on other sites More sharing options...
zeropolis79 Posted October 30, 2018 Share Posted October 30, 2018 You were quite fast https://www.youtube.com/watch?v=aU5_zy3Kd2U I gave it a going over then did my review video. It helped I know the game from the Amstrad CPC.. I did notice a few differences like the lack on an anka on the plane at the beginning (it was there on the Amstrad version but I presume it wasn't on the C64 version) Quote Link to comment Share on other sites More sharing options...

I did notice a few differences like the lack on an anka on the plane at the beginning (it was there on the Amstrad version but I presume it wasn't on the C64 version) That "invisible" ankh is there on the plane's wing in all versions I think, it's present also in Atari version. I think you eventually didn't enter that back entry to the pyramid, just tried to shoot at it? Quote Link to comment Share on other sites More sharing options...

zeropolis79 Posted October 30, 2018 Share Posted October 30, 2018 Was mine the first? The ankh was visible on the CPC version - it was under the wing.. As for the back door, I couldn't remember how to open it. Quote Link to comment Share on other sites More sharing options...
+Adam+ Posted October 30, 2018 Share Posted October 30, 2018 (edited) Was mine the first?The first with commentary The ankh was visible on the CPC version - it was under the wing..I only saw CPC version on this video - watching it from 0:40, I don't see the ankh there and it looks like that player wasn't sure where it is: As for the back door, I couldn't remember how to open it.It looks different than the front door, but it's also already open.

zeropolis79 Posted October 30, 2018 Share Posted October 30, 2018 Ah, I know Amstrad Maniaque's videos. When it comes to CPC matters, I know a lot. When I play it next, I'll take a look and make sure my memory is not faulty. Hope my video shed good light on the project. 1 Quote Link to comment Share on other sites More sharing options...

If possible and you have time for that, it would be great to have both load/save and further optimization for 128+ KB ATARIs :-) 1 Quote Link to comment Share on other sites More sharing options...

emkay Posted November 1, 2018 Share Posted November 1, 2018 I really wish I had time to play this - incredible game that I wish was ported back in the day Actually, they closed a gap of a missing genre on the Atari, and did it very well. The sad part is that such games could have been much more advanced after one of those games had reached the Atari back then. Quote Link to comment Share on other sites More sharing options...
José Pereira Posted November 1, 2018 Share Posted November 1, 2018 (edited) And wait untill next Saturday when in SillyVenture will be released a port of another old other 8bit machines game that also features some never seen on A8 things. I can't reveal its name now but though there will not be the final version is still playable and mostly done. You just have to wait less than 2days ...

Lost Dragon Posted November 4, 2018 Share Posted November 4, 2018 I really wish I had time to play this - incredible game that I wish was ported back in the day This kinda my viewpoint. I've not touched an A8 Micro in so many years, but i follow the scene with a real sense of hunger. If titles like this had made it to the Atari at the time, i doubt very much i would of moved to the C64, just played the games on my mates C64, but stuck with my trusty 800XL.

Lost Dragon Posted November 4, 2018 Share Posted November 4, 2018 There was a Spectrum Only sequel to this as well i believe. Never tried it. Quote Link to comment Share on other sites More sharing options...
+Adam+ Posted November 4, 2018 Share Posted November 4, 2018 (edited) There was a Spectrum Only sequel to this as well i believe. You mean "Total Eclipse II: The Sphinx Jinx" - the same engine, the same look, but different map and puzzles. That sequel also exists for Commodore and Amstrad CPC. C64 version looks like and sounds like that (the same music as in the first part): Edited November 4, 2018 by +Adam+ 1 Quote Link to comment Share on other sites More sharing options...

+Adam+ Posted November 4, 2018 Share Posted November 4, 2018 Is it more of an expansion rather than true sequel? Yeah, that's why I think it was published only as a bonus with some Total Eclipse editions, not as a standalone game (as far as I know). 1 Quote Link to comment Share on other sites More sharing options...
