The discussion about High Score Cart game values in the 'Space Invaders 7800' thread prompted this thread. I thought we could have one place where we could put all of the High Score Cart game values. I'll post what I have:

Original Releases:

• Asteroids - $49,$6C
  
• Dig Dug - $41,$42
  
• Centipede - $01,$01
  
• Galaga - $86,$26
  
• Joust - $8B,$23
  
• Ms. Pac Man - $80,$01
  
• Xevious - $8A,$0F
  
• Food Fight - $23,$23
  
• Robotron 2084 - $20,$84
  
• Desert Falcon proto - $00,$00

My Hacks / Homebrews:

• Asteroids Deluxe - $49,$6D (Hidden Asteroids codes are $49,$6E)
  
• Space Duel - $49,$6F
  
• Pac-Man Collection (includes seperate HSC codes for each variation of Pac-Man) - Range: $8X,$01 - $AX,$01 Legend: $8x = Standard Speed, $9x = Fast Speed, $Ax = Button Speed), and the first three bits of the second nibble are the game type, and the last bit is 'Plus Mode'. Looks like I use the same code for Ms. Pac-Man as the Atari Version. Damn - OLD VERSION with TIA Sounds only
  
• Updated version of Pac-Man Collection (including additional mazes and Pokey Sounds): $8X,$0F
  
• Space Invaders - $19,$80
  
• Super Pac-Man - $80,$02
  
• Jr. Pac-Man - $80,$03 and $80,$04
  
• 'New' version of Ms. Pac-Man (description found here) - $80,$00
  
• FailSafe - $09,$00
  
• Crazy Otto - $80,$08
  
• Super Circus AtariAge - $0A,$00
  
• '320' Mode Pac-Man - $80,$0C
  
• '320' Mode Ms. Pac-Man - $80,$0F
  
• Crazy Brix - $0A,$01
  
• Meteor Shower - $0A,$02
  
• Moon Cresta - $0A,$05
  
• Scramble - $0A, $07
  
• Rip-Off - $0A, $06

Ms. Pac-Man Hacks (these were meant to be abandoned once Pac-Man Collection! came about, so these values clash with the values in PMC)

• Dual Pacman - $8C,$01
  
• Hangleyman - $86,$01
  
• Ms Pac Attack - $84,$01
  
• Ms. Pacman Fast - $85,$01
  
• Pac Polux - $8E,$01
  
• Pac-Man - $82,$01
  
• Pac-Man Plus - $88,$01
  
• Ultra Pac-man - $8A,$01

Excellent Homebrews by other authors:

• BonQ - $22,$DD
  
• BeefDrop - $22,$DC
  
• Froggie - $10,$01

Anyone who knows some other values or has done homebrews, please add to this thread, and I will update this list.
Thanks!

Make sure you don't miss the Original Releases that I updated (since it is in quotes).

[PacManPlus]

Thanks Shannon!

List updated.

Is this list now complete? Was there High Score Cart support in Froggie?

[Shannon]

Yer welcome!

I suppose. As long as that list of games that support HSC was complete. I tried Froggie and it didn't seem to have any high score support yet.

Is that the values you plan on using? Or is there a Froggie file out there that I don't have? Could you be so kind as to point me in the right direction?

Thank you.

I already use this values but I don't think I published the HCS Version (really not sure about that)

[PacManPlus]

... waits for HSC version of Froggie to be posted


BTW, with regard to the HSC codes, certain bit valus seem to mean different things.

For example, somewhere in those two bytes there is a setting for if the score should multiplied by 10 (like for Ms. Pac-Man), or left alone (like for Space
Invaders). Don't know which bit(s) flag this. I wonder if there are other bits with specific meanings in those two bytes?

I don't know much about the high score cart. But if it's just a storage device, and the values are only going to be read by the game which stored them, then each game could use any formatting it chooses. So the format would potentially be different for each game.

[PacManPlus]

Thanks

The only reason I say this, is because when I used $19, $80 originally for Ms. Pac-Man, the score showed up in the HSC divided by 10 (which is how it's stored in the game). When I went back to $8X, $01 it showed up correctly. So there is something (I believe in the second byte) in the HSC telling it to multiply the score by 10 for certain games.

[mimo]

A little off topic, but could original games that do not support the HSC be hacked to allow use?
Would be nice to keep track of all my low scores

[gdement]

Oh, I somehow misread what 2 bytes you were referring to, and assumed there were 2 bytes for each score entry. It should have been obvious from the context you were talking about the game ID.

That is weird.
If we can fill in a bigger list of what games have their scores multiplied, then the pattern should probably emerge. Either that or the HSC source code. I think it's available, but I'm having trouble finding it.

[PacManPlus]

Ok - I got it.

After some experimenting, I found that bit 7 of the first HSC Identifier byte (in Ms. Pac-Man, the $80) determines if the score should be multiplied by ten or not.

e.g.:

76543210

1XXXXXXX = Multiply score by 10
0XXXXXXX = Use score as is

Hope this helps!

Super Pac-Man: $80,$02

[PacManPlus]

Just added Jr. Pac-Man: Jr. Pac-Man - $80,$03

I think we have everything, no?

[PacManPlus]

Super Circus AtariAge - $0A,$00

Unfortunately I no longer can update the first post.

See if you can edit it now.

[PacManPlus]

Thanks, Mitch - I can edit now.

[PacManPlus]

Bump - Updated list above. Guys, anyone who is creating games for the 7800 and is including HSC support, please let me know the ID bytes so we can keep this list updated. It would be great not to step on each other's toes here.
