I have just tested the game again as described with the HDF version and only one disk drive, unfortunately with the same result. I also noticed that the game does not run without additional memory of at least 64 KB (Z2 Fast). For the test I had set 1MB, a completely normal configuration for memory extensions at the time. I have attached the corresponding error message here as an image.

I would also like to add that I only played such games with 8 MB Fast RAM usually, just to avoid memory bottlenecks with WHDLoad and HDD games. Of course, the chip RAM was only preset to the usual 2 MB, see the Workbench memory status in our video. As far as compatibility goes, I rely on the statement of "Toni Wilen", the author of WinUAE. For years I have not found an OCS/ECS game or demo that does not run with it, which is why I now assume that it is 100% emulated. The AGA games and demos that I have tested over the last 4-5 years also ran perfectly with it, but of course I couldn't test all releases. However, there are sometimes configurations that do not correspond to the same setting of the computer on which they were programmed. That is why I am happy to offer to provide you with the configuration I use. 🙂

Excellent, thanks, the error message pinpoints exactly what happened.

So, I did a special version for you that should work (let's cross our fingers). In this link.

It's a very rare issue! You can check on YouTube now, many longplays and live streams that didn't had that problem, like this one, for example.

Also, the problem doesn't seems to happen on FS-UAE, it only happens on WinUAE.

So, what I did was to reduce the number of candles and objects on the level by about 10 to 20% (the error message is about that: max number of objects/limit).

If it still crashes, I'll reduce even more! Don't give up! ;-)

Thank you very much for the quick update. 🙂 Unfortunately, the problem still occurs with exactly the same error message (tested with the HDF version). Have you really uploaded the new version to Google? Anyway, I used exactly the same configuration and teleported to world 5 with "F5" as before after starting a new game. Then I refreshed my energy with "H". Perhaps there is a problem related to this or with any driver like AHI that is preset in my OS 3.1. (I still can't really believe that it's because of WinUAE, since it supposedly works for you, even with an older version). This evening I will test the game in the regular download version on my real A1200 with Blizzard 1260 (68060 @ 50 MHz, 64 MB RAM), as this is also bothering me, and then complete this text accordingly. I would also like to send you my WinUAE configuration. However, I need your email address for this.

I did another version, this time I increased the actor count. The error message says that the limit of 32 has been breached, so I increased that limit considerably. You'll see the number on the score panel at the top, right next to the word 'enemy' (it's temporary, just to make sure you're on the right version and can see the actor count). Link here.

(Edit: added new modifications around 03:55 AM GMT, please download again if you got it before).

I had reports about other issues from other players, but nothing on that stage. They're more related to CD32 version, which isn't your case. But let's see what happens with that increased number of actors on this new version I'm sending now.

Your WinUAE config isn't needed now, because I was finally able to make it crash on my configuration too. I also recommend that you avoid leaving too much candles and objects behind (you must destroy as much as possible) because they accumulate on the level and cause the limit to be more easily breached. If nothing works, I may try to compile the project on other versions of the engine, older or newer, until we find a version that works for you. Thanks again!

Unfortunately no changes. It still crashes with the same error message. Only the number in the "PC:" line changes after each crash. I have now tested the game in the regular, current download version (LHA) on my real A1200 via a PCMCIA CF adapter and... what can I say? Exactly the same crash at almost the same point in the first level of the 5th world. So it is definitely not a WinUAE problem.

I started the game on my real A1200 with only 2 colors in the Workbench from the CLI and got the same error message as on my WinUAE setting, see here:

Since I actually tend to avoid certain enemies when using trainers and not destroy everything on the screen, it seems that my gaming style has revealed this bug . 😉 In any case, I wish you the best of luck in fixing the bug and am happy to be available as a tester again at any time. And I also stand by my word when it comes to the final rating of the game. 🙂

Definitely not your Wb or chipRAM, that were assumptions I took based on the most common errors described. Like an airplane accident, it's generally caused by a conjunction of factors: the limit on number of actors, your play style, and now a new discovery:

The bones launched by the red skeletors were not being removed when they go off screen, so, they were *also* accumulating. So, that was the modification I did on the post edit. But to confirm it further, one more test, this time I removed them completely (applying the Muntzing method):

https://drive.google.com/file/d/15F00WcMoPLme680Ers_JTh0AcENxTuiG/view?usp=shari...

Also in the plane accident analogy, at this point I'm completely exhausted, have put many sleepless hours on this issue, and I'm prone to commit errors at this point. Like exhausted pilots do when under absolute stress. So, I may even put wrong files up for your testing (this time is just the WHDLoad on the link above, to make sure). Sorry, but doing an Amiga game of this scope, for free as a single programmer, no matter how advanced are the current tools, is like swimming against a very strong tide, several miles from any beach on open ocean. All this for a free game on a very niche platform. That's important to have in mind when it's about game rating.

I understand that very well and have great respect for so much programming skill, but in the end I always have to base my overall vote on the finished product that I have at the time of the review during a broadcast. Take your time when looking for and fixing errors and give yourself a few days of rest. As you say, this is a hobby project for a free game and there is absolutely no time pressure, especially since the game is actually already finished. 🙂 Apart from that, even in the boom years of the Amiga there were serious bugs in commercial full-price games that could not be fixed with a patch without starting a costly exchange campaign (e.g. Turrican 1). I am very happy that there are websites and projects like this one where the community can provide active help, not just error tests and suggestions for improvement. Otherwise such great games and our live streams would not be possible in the first place.

Back to the game: Unfortunately nothing has changed with the current update, despite the missing red skeletons. The game crashes again in the first level of the 5th world. 🙁

Well said!

But about the game status, it's "feature complete", that doesn't means it's "complete" as a full release. Perhaps there's a misunderstanding going on. It's technically a beta (all the content is in it, but it's still untested and has issues to solve).

Also worth saying, that the internet today is very biased *against* the Amiga. You can see issues and glitches on full-price commercial console games released (search for "Super Castlevania SNES moonwalk" on YouTube for example) but the internet seems to turn a blind eye to that - if that was on a free Amiga game, its author would be harshly criticized! Because there's a sort of herd mentality, mostly negative, regarding the Amiga today (internet "revisionism"), which is very frustrating and disheartening.

Finally, check the status posted on the devlog, your error has been reported there, work continues:

Thanks!

Yes, I can understand that and it is sad to know that you have obviously had to go through similar experiences. That's why I admire all the people who are still putting so much effort into it. And of course I don't want to give the impression that I have expectations, I just want to help with testing. If there have been any misunderstandings, I am sorry, because I actually assumed that this was a completed project, as it was announced on Indieretronews, see here: https://www.indieretronews.com/2025/01/castlevania-aga-castlevania-for.html

I wish you the best of luck with the completion and am always happy to help with further bug tests. Just let me know if there is a new version for testing.

No problem, Neil at Indie Retro News wrote that it was feature complete as the main headline, I know it's easy to confuse and just think that it's fully complete. That's why I did that devlog post here on Itch.io, but for anyone who plays it becomes clear that it lacks testing. :) So, again, thanks very much for your testing, and sorry for my insistence, but here's yet another update for your testing, this time fully concentrated on your world5 problem:

https://drive.google.com/file/d/12XoU88mNCO34DtespfZKbW7JCwB_HPZq/view?usp=shari...

What I did this time was profound, I changed for another version of the engine. It adds other minor glitches in other parts, like for example, the character can slide on your knees if you are walking then press down. But the overall performance may be improved and best of all, it's possible that the world 5 crash doesn't happens. The minor glitches will be fixed in time. Scorpion Engine is an experimental, on-going project, it has several versions and is being constantly updated. I was using a stable one, from a while ago, because it was stable for me. But it is obviously not stable for you. So, it was the recommended action by the friends at Discord: to change to another version and see if it works!
