Harem Challenge [Cubo CD32] - Playable on Amiga CD32 and emulators for first time!!!

[DamienD]

Heya guys,

Some excellent news... finally the 2nd "Cubo CD32" game has been patched and is now playable on an "Amiga CD32" console or via emulation

Many thanks for the details on what to patch must go to the man ross

So, following the vital information in this post, I've now undertaken the following:

• Downloaded the "haremchl.chd" file for MAME.
• Used "chdman.exe" to extract ".BIN & .CUE" files.
• Used "HxD.exe" to find / patch the specified area.

Buttons are as follows:

• RED: Leave starting postion.
• BLUE: Retreat back to starting position.
• GREEN: Shoot bullets.
• FORWARD: Insert coins.

For now, grab the game from here but will probably also upload onto the EAB File Server for preservation

[nujack]

Awesome!!! Great work guys!!!
Will try it out now on my CD32.

[Gzegzolka]

Awesome. Will try it tomorow under winuae

[DamienD]

As this was a bit tricky i.e. see ross's post here about leaving out the "subchannel data"...

I asked him to kindly please check the files I've patched / uploaded; thankfully I receive the following reply:

One thing I noticed when looking at this game's files is the following:



Ran it via MAME and entered Service Mode. Sure enough there are options for "Soft" / "Erotic" / "Porno":



I wonder how you can get into Service Mode on a CD32 or would the image need to be patched for each option?

[DamienD]

Ok, using MAME I've created an NVRAM file for each option

For emulator users just extract the "cd32.nvr" from either of the following directories in the attached archive:

• Erotic
• Porno
• Soft

As for use on a real Amiga CD32 console; someone else would have to advise on how to get the NVRAM across as I have no idea...

[Gzegzolka]

I have run this game in winuae and at start it show service mode so I can set what photos I want watch.

[DamienD]

Interesting, I wonder why you can get into the service mode? I definitely can't, the game just boots past the "System Setup" screen

earok mentioned something similar here in the CUBO CD32 Games.. thread:

The difference is WinUAE allows you to tweak the dipswitch settings (you're prompted to when the game loads) but on a real CD32 it skips the menu and loads the game directly (presumably with whatever the default settings are).

Toni's response was here:

Followed by earok again here:

[Toni Wilen]

It asks for service mode parameters if nvram is empty?

I've deleted "cd32.nvr" so that a new one gets created when starting emulation.

Still no Service Mode upon booting though...

[Gzegzolka]

It show service screen each time I run it and reset it. It create entry in nvram.

Update - I attach my nvram from winuae 3.0.0

[nujack]

What do you mean? Test on my CD32 brings up the Service-menu each time:

Hi Toni, has nothing to do with NVRAM.
You changed return value read from not mapped memory area after v3.2.2
In this particular case from $800003, used by CUBO for SW switch.
The service mode is triggered by bit 6 and the value returned (#$75) start it only by chance.
In new versions the returned value is 0...

ross

Another day, another hack
Is already in good standing in the previous message

We need a consistency to emulate location $800003, particulary the bit 6, and valid for every Amiga machine.
What's the best candidate? Yes, the everytime used CIA-PRA location!
We are extremely lucky: bit 6 is /FIR0, your friend LMB and is a negated signal. Better than ever!
So we need to find where the check in SETUP is carried (and also on exit) and substitute.

For your pleasure:

1252F0EF: 800003->BFE001

(enter setup)

12530F85: 800003->BFE001

(exit check)

Works on real CD32 or every version of WinUAE.
Default behaviour is enter in Service Mode; if you keep pressed the left mouse button old value is read from NVRAM.
You can exit from Service Mode with LMB
(or simply, if you don't have the mouse connected, use the regular joypad button in the other port).

Enjoy,
ross

[Toni Wilen]

So CUBO does have some extra hardware after all.

At least candy puzzle seems to read other bits. Service menu says "SW7=ON TO EXIT" so apparently there are at least 7 (perhaps 8) toggle switches, one for each bit.

[Solo Kazuki]

Yes. According information there was expansion board linked to JAMMA adapter. There are 8 dip switches on JAMMA adapter (top-left side of photo).

[ross]

Yes, and confirmed that SW numbering is 1 to 8 (bit 6 is SW7=SM).

Cheers,
ross

[Neil79]

haha DamienD this one is a bit too raunchy for our site But I'll do a big social media plug

[DamienD]

LOL

...only if you change dip switches; nobody is forcing you to

[ElectroBlaster]

Brilliant thank you for sharing. This is what the Amiga is about! sharing and archiving so it is saved forever
