HELP: Three Vic20 games I'm looking for

Spectrum · Post by **Spectrum** » Sun Dec 30, 2012 3:06 am

Hi guys,

I've recently got the MegaCart and I also bought an Infinity SD device for my Vic20 (if you don't know what the Infinity is, take a look here: http://www.manosoft.it/?p=1&lang=en ).

However, although I now have all the games and software I need on cartridge (thanks to Bryan's Megacart) I'm still looking for some games I highly appreciated when I was a kid.

BLOCKBUSTER: an excellent Pengo clone imho. The .prg file that's online don't have any music ;__; I've found a .tap file that works on emulator but I don't know how to turn it into a .prg file to use it into a real Vic.
Does someone know where I can download the game (with the music working) ?

DODO's LAIR: one of the first games I ever played on the Vic. It's a strange shoot 'em up with scrolling from the right side toward the left side. I really have no clue where to find it.

JUMPIN JACK: an excellent frogger clone. I played a lot on this game.

All these games are for the unexpanded Vic20.

Thank you for any help you can give me.

You can get BLOCKBUSTER here. Just unzip it to your SD card and LOAD "BLOCKBUSTER",8 and RUN... I don't know if you need the .prg extension on it or not, but this works fine from xvic emulator. Press a key will load & run the BLOCKBUSTER.F binary.

Thank you, Rhurst! I'll check it immediately on the real Vic.
I also tried Repel on it, but it doesn't work well. Did you ever tried Repel on a true Vic20?
Bombs from the invaders never reach the lower part of the screen.

Hmmm, works for me... I wonder if REPEL works only on an NTSC VIC?

Good point.
It could be.
On VICE, Repel perfectly works. On the true PAL hardware it doesn't.
Too bad, 'cause I love that game...

I'm gonna try Blockbuster on the real VIC now...

Blockbuster doesn't work as it should, Rhurst.
The games works well, but it have no music.
The original had music ( http://www.youtube.com/watch?v=0hgx2uILLb0 ).

I have a blockbuster.tap file that have music on the VICE emulator, but I don't know how to load it in the real hardware.

All of those games will be in Gamebase20. I will have to check what version(s) of Blockbuster I have to see about the music.

EDIT: Having checked, I think whoever cracked it may have removed the music to "gain" enough memory space to save it as a PRG. Seems an odd thing to do I suppose. Unless the crack turned off the music for some reason.

I think I know how to fix that game, but there is not enough free RAM. :-/

I remember trying to play Dodo's Lair recently.
It's in GameBase v02 in "extras\tap\unexp taps".

OK here is the fixed version!
Enjoy

Here is how it’s done:

Code: Select all

 	* = $1001
			;original BASIC loader without ml part
!binary"loaderwoml.prg",,2

	* = $110a	;4362

	ldx #161	;restore the tapebuffer
-	lda tb,x
	sta $033c,x
	dex
	bne -

	lda #3
	sta $033c

	lda #$ff
	sta $b9		;current secondary address
	lda #$09	;length of filename
	ldx #$07	;address of filename lo
	ldy #$10	;address of filename hi
	jsr $ffbd	;set file name                    
	lda #$19	;put address $19ff on stack
	pha		;after load, the pc is set to stack + 1
	lda #$ff	;which is $19ff + $1 = $1a00
	pha 
	lda #$00	;flag load = 0, verify = 1
	jmp $ffd5	;load after call setlfs,setnam    

tb			;tapebuffer data

!binary"tapebuffer",,2

Good work

If you can make PRG files from the TAPs of Dodo Lair and Jumpin Jack, that would be great for the OP too. I don't have PRG for either too, so I'd be including them in GB20 as well.

And why not Sprite Invaders?

Thanks, I’ve looked at the TAPs of Dodo Lair and Jumpin Jack (from TOSEC). Somehow WAV-PRG (3.6 and 4.0.1) give a lot of errors or don’t extract the PRG’s at all from those two TABs.

With BlockBuster.tab I got two PRG’s without errors.
Perhaps if there are some other versions?

Hi guys!

First of all: thank you everybody for the infos and for your help!

LORDBUBSY: thanks a lot! Now I have Blockbuster fully working!!! I feel like a kid! Tonight I'll turn on my VIC20 and I will play it!

Too bad you couldn't do the same with Jumpin Jack and Dodolair. I am slowly collecting prg files to load them in the real VIC via SD card.

Rhurst, thank you very much for your link to Sprite Invaders! Superlative!
I am already a BIG fan of Omega Fury and Quickman. Now I have another great game to enjoy!

Finally, too bad for Jumpin Jack and Dodo Lair... it could be possible to create a prg file from the original tape?

Kweepa · Post by **Kweepa** » Tue Jan 01, 2013 3:01 pm

Dodolair has 5 prgs on the tape, although I suspect three of them are prgs in name only.

Code: Select all

 1 DODOLAIR
11 DODO2
 3 CHARS
15 CODE
15 CODE

Unfortunately it appears to be a hacked version, because the game doesn't end when you run out of lives.

Creating a d64 is non-trivial.
