[WIP] Phoenix conversion

[tomcat666]

Great Port... perfect in fact.

Would it be possible to add an option to disable UP for the shield (so only 2nd button would do that) - I tend to accidentally press up and screw things up

[jotd]

thanks everyone! no9 sent me the music I still have to listen to it. He was modest but I'm sure it will be perfect already!

Yes, planned, and also PAUSE!

[JoeJoe]

Congratulations on the successful port. It's impressive how quickly and precisely you work.

[saimon69]

It is me or the fire sound effect in saberman demo is reversed?

[jotd]

yes, it's a mistake. Fixed!

Some quite fast but deep RE and transcode from your servant, solving errors & link problems, and all (and after a graphics mockup), and at FIRST boot the amiga version of the game displays this:


Attachment 81971

not bad for a few evenings work.

Great job!
Is the z80 translator open-sourced by any chance?

Looking forward to playing this game, I remember spending wasting a decent amount of coins on the arcade version when I was a kid…

[jotd]

Yes, the translator is open source like everything that I build for Amiga

https://github.com/jotd666/amiga68kt...ols/z80268k.py

Don't expect that things work out immediately. There are a lot of manual rework to perform. But with this tool I could make games boot in just a few evenings, where manual transcode would require weeks.

Thanks for everything JOTD. Here at IndieRetroNews, I bow before your awesomeness

I only see a few Your code, but better dont use code, like this:

 movem.w    d1/d2,-(a7)
  ....
 
 movem.w    (a7)+,d1/d2
 rts

Because value for source and destination registers can be different.

This is better version:

 movem.w    d1/d2,-(a7)
  ....
 
 move.w    (a7)+,d2
 move.w    (a7)+,d1
 rts

Exactly better is always using movem.l than movem.w.
Movem.w is for me only good for coding tricks.
Or You can have problems with program code.
Many coders dont know, how works movem.w

[jotd]

I didn't know that and I'm very surprised (besides, it seems to work properly on the 10+ games I used it on).

Anyway there's another argument about not using movem in this case: the performance of 2 move instructions is better than a movem with 2 registers. Preserving the flags is not interesting in most cases anyway.

i tried in WinUAE with A500 config (512k+512k) and loading from floppy stop to load at track 40 (not in crash or freeze, but simply not load more).
I tried with 1 MB chip ram, but same thing.

WHDLoad version it works, but after i play for some seconds, the screen become black.

However, i will wait more stable version

[jotd]

Strange as I tried with winuae 1MB config and it worked. We'll sort this out, I'm sure of it.

Version with no9 music will be released maybe tonight.

@JOTD

The game works corretly on my differents systems (ADF & WHDLoad)

I Tried it :

1) My A500 (Rev.6A) with an ACA500 Plus ADF Tried succesfully with :

a) Profil KS 1.3 512+512 in a Gotek Drive
b) Profil KS 1.3 1MB Chip (emulation via ACA500PLUS & AGNUS 8372A)
c) In Workbench With KS 3.1.4.1 under WHDLoad

2) Succesfully Under another A500 rev.6A ONLY (512k+512k) KS 1.3 and a Gotek

3) Succesfully on my A1200 in Gotek Drive mode (ADF) & with WHDLoad

4) Succesfully in WinUAE Profil Mode A500 KS 1.3 for ADF (OCS, ECS, ECS 1MB Chip) & WHDLoad too.

[jotd]

thanks for those tests. I have fixed more issues, and added more features. Updated on itch just now

[PascalDe73]

Sorry JOTD,

With Your latest ADF version (Tonight) it crash on real my A500 ACA500Plus

On my A500ACAPlus in A500 Profil with ADF GURU ERROR POWER BLINKING and Reboot.
In mode A500 512+512 and in mode A500 1MB CHIP.

On my A500ACAPlus UNDER WHDLoad just after Slave scrren with option I obtain a black screen and nothing else ... no sound and Quitkey doesen't work ...


Please could You have a look

[jotd]

Yikes! just tested on real HW with whdload but 68020+. I guess some non 68000 code has slipped through, since previous version was OK.
Sorry for this. Will fix tomorrow.

Confirmed: 68000 or 68010 just freeze if I set 68020 on the same configuration on winuae it runs. I think I know the problem

Ok Thanks,


At tomorrow evening to have a new test

[Seiya]

ok, now it works also for me

[jotd]

Yes, I have removed a memory corruption in the meantime, but introduced a 68000 issue (which isn't word at odd address...). Will debug tonight.

[DanyPPC]

Many thanks Jotd

I'm having fun with this old addictive arcade game.
I'm child again
