WHDLoad for Andromeda Mission (AmigaDOS)

apex · 23 December 2021, 15:25

Hello,
who is willing to do a slave for Andromeda Mission? :-)
The game is in AmigaDOS format, which should make it quite easy.

http://hol.abime.net/2494

I was able to make an IPF file.

jotd · 23 December 2021, 18:20

started it, running. There's manual protection to remove, though.

apex · 23 December 2021, 22:50

There is a stupid question “who made the game” at the beginning.

But if you know it was Daemonware, it is easy. Saw no other protection till yet, but the guy who cracked it 30 years ago said there was a copy protection that you cannot duplicate the disk.

“I only have a vague memory of the crack (was 33 years ago), I mean the copy protection checked with trackdisk.device if the track was readable, I just formatted the track and made a BEQ.s out of a BNE.s. Easy Frag.”

Just trying it out... I was asked "How many levels does Mission Andromeda have?" so there seem to be several different questions.

Haha, all the question are directly visible in the executable.

- How many photos are on the backside of the packaging?
- How many levels does Mission Andromeda have?
- Which color is the packaging?
- Which color has the Mission Andromeda text?
- What is the first word below the upper left screenshot?
- How many enemies are in the upper left screenshot?
- What is included with Mission Andromeda?
- How is the producer of Mission Andromeda?

So I guess there's no disk protection after all.

Here's the protection code:

jotd · 23 December 2021, 23:56

yeah, found that too, by finding the random routine and the text display routine

and I confirm that there isn't any disk copy protection. Or this is a sneaky one, not at start... I doubt it.

plus IPF can be read in DOS mode without issues.

Zoned a beta whdload installer

Will check, nice Christmas present, thank you! :-)
It was my first game ever.

mnemo · 24 December 2021, 10:59

Works, copy protection can be skipped, but the game runs too fast on an 680x0 (as stated in the readme). Good start, though! Thanks!

jotd · 24 December 2021, 11:03

probably needs speed regulation. Damn that's annoying.

Also needs an icon.

apex · 24 December 2021, 12:37

Installer using the IPF works fine.
But it has on 030 and 060 the same speed problems. 2 second normal, 1 second massive speedup, 2 second normal and so on.

jotd · 24 December 2021, 14:05

I think I can fix that. Game is using wait bottom of frame and probably wrongly assumes that 40 ms has passed when sometimes it's only 20 ms because of cpu speed.

Seen that a lot in old games that expect to run at 25 fps but sometimes run at 50 fps unexpectedly.

jotd · 25 December 2021, 00:23

zoned a new version. Tell me if the speed regulation works. else I'll add another regulation.

Aladin · 25 December 2021, 02:07

The version on HOL does not have the status panel at the bottom of the screen. Was it a preview on HOL?

There are two versions and I'd prefer the original one without the ugly panel.

Aardvark · 25 December 2021, 10:04

The graphics in the panel version is 222 pixels high, and the non-panel version uses 170 pixels, so it's likely an NTSC release. Actual gameplay area is same size in both versions.

apex · 25 December 2021, 20:38

This version was PAL, language is a mixup of German & English.
But I know there was also a NTSC version.

I will test it tomorrow again on 030 & 060.

jotd · 25 December 2021, 21:13

I have released the official version too. Regulation seems to work. Added trainer too

apex · 26 December 2021, 10:34

Thank you.

apex · 26 December 2021, 12:04

Tested it now on 030. Tooltypes in the icon were missing.
First level is ok, but starting with the second level it seems too fast.
Or I am getting old?

Also third level… came there only using the trainer.

So no slowdowns anymore, but a bit too fast in the higher levels?

apex · 26 December 2021, 13:19

On 060 you are lost in the second level.

Also interesting: enabling unlimited energy leads to a not firing boss in the first level.
Not always, but in my tests he was only firing sometimes and the other times just moving.
