Mega Typhoon WHDLoad

[modrobert]

What is the button or key to continue the game in Mega Typhoon at the "Yes / No" prompt where it reads you have 6 credits after "game over" and it times out after 10 seconds?

This WHDLoad slave:

I'm using a regular two button joystick (not CD32 joypad), none of the fire buttons works. 'Y', 'N' and 'Enter' keys on the keyboard fail as well, but you can change selection between "Yes" and "No" using left and right on the joystick.

I just tested it myself and it seems to be a bug of some sort. I tried the ADF version and pressing the fire button to continue works just fine with that but not on Whdload version.

There's a problem with the WHDLoad version.. Retroplay needs to check it out

WHDLoad version wont work with v19.0 (Black Screen on loading screen) - I Dropped it to WHDLoad V18.8 and it game booted in WHDLoad

Fire Button on Continue Screen Does not work with WHDLoad with version v18.8 or below.

Fire Button on Continue Screen works with Adf

Quick hack fix i copied over all the game files from Mega Typhoon (1996)(Nordlicht PD)[f 100% ross][h TRSI][t +5 CRX].adf into the WHDLoad Version replacing all files and with WHDLoad V18.8 Game seems to boot and also Fire Button works on Continue Screen..

Ill shoot Retroplay a message about this...

Aha, so it was a bug, was thinking it was some special key or button combo. Thanks for checking. I will try the "100% ross" version.

EDIT:

I tried replacing the files with the "100% ross" version running WHDLoad V18.9 and fire button now works to continue. Thanks again.

However, after booting my A1200 from the floppy version, besides the nice cracktros (and centerfold), I noticed the game runs smoother without vertical graphics jitter compared to WHDLoad, so sticking with the floppy for now. EDIT: The jitter still exists in this version as well, it's just random.

EDIT2:

After testing the WHDLoad slave v1.3 a bit more with the "100% ross" game files, the vertical graphics jitter sometimes goes away if the game is exited with 'Esc' key and a new game is started ("insert coin"), perhaps something wrong with the graphics initialization.

[modrobert]

The high frequency vertical jitter, roughly one in pixel height, making the surface scroll look a bit fuzzy, can be triggered on all versions; "WHDLoad supported game data", "100% ross booted from floppy" and "100% ross as WHDLoad data" on my A1200 (see sig for details). I found an easier way to fix and trigger it, use 'P' on keyboard for pause during game play, then unpause, you will see the jitter disappear (smooth vertical scroll) and come back sporadically (jittered vertical scroll), once you leave it in certain state (without pausing again) it will continue that way. When seen the jitter is in the slow automatic vertical surface scroll, not about moving the ship around using controls causing fast scroll.

Also, sometimes after "game over" when reaching the "continue?" screen there are big green vertical bars over the graphics (sprites perhaps? not sure), menu operation still works but looks corrupted until new game is started. This also happened in all three versions mentioned previously.

I think these could be original game bugs (common with Amiga games), or perhaps related to the A1200 chipset (AGA, assuming this game was designed for ECS/OCS), but mentioning anyway.

[modrobert]

I modified the WHDLoad slave source code and compiled (using Barfly) a fixed v1.3 where the "CONTINUE?" fire button works.

Basically I make use of the existing _bsr_controller_type() call in 'ReadJoyPad.s' to establish if we got a joystick or not, and then load separate WHDLoad resload_Patch() list depending of which type of joystick is detected.

cmp.b   #0,(controller_joypad_1) ; this is true for joystick, not joypad (CD32)

I would be happy if someone can test if using a joypad still work with this slave because I don't have a CD32 joypad to test with.

This slave expects the WHDLoad source version of the game where the selectable trainers work (not the 100% Ross version).

JOTD,

If you happen to stumble across this, then feel free to make a new official release of the slave, then maybe the supplied source code will help (or not, up to you).

The attached archive includes slave binary and source code.

Tested on real Amiga 1200/030 OS 3.2 and joypad KTRL CD32, but no success.

The buttons don't work on Continue screen.

Aha, OK, so the fire button didn't work with joypad in original v1.3 slave either I suppose, because haven't made any changes to that part. I was assuming it only fails when using regular two button joystick which is fixed now.

Alright, will see if I can fix the joypad problem as well.
