Only CPU regs are used, enjoy

Sweet! I will check it out asap!

Well it's unfair! The CPU had a faster bar...

congrats, remind me my first md demo back in 2000

the good old trick of the second bar with the Y of the ball

In a moment of boredom I've opened the BIN...

0x2EA:

Code: Select all

Is this actually interesting ???

LOOL.
Some times it is, depending on what you can find (secret/cut stuff/leftovers).

*(VDP registers at 0x2C4A)*

BTW the phone number is... EPIC: 1-800-EATS-HIT

Code: Select all


   I also have another secret e-mail address .... 
   ...  but I won't tell it, Ha :P

Dang! I was looking for it...
Next time put some code in the vectors' space, to be even more wierd...

Does POS happen to mean Piec& 0f $hit?

But wait... You also released a 2007 Xmas MD proggy... Time to dig! Let's see what easter eggs it has inside, heh...

Bah, sadly not as great as this one, and segane hadn't none either.

It seems that PONG!RAM realy don't use any RAM (except VRAM and CRAM of course).
http://rapidshare.com/files/186931112/PONG_RAM.zip.html

Code: Select all

ROM:00000352                 lea     (loc_35E).l,sp
ROM:00000358                 jmp     (loc_90A).l
ROM:0000035E ; ---------------------------------------------------------------------------
ROM:0000035E
ROM:0000035E loc_35E:                                ; DATA XREF: RESET:loc_352o
ROM:0000035E                 lea     (loc_36A).l,sp
ROM:00000364                 jmp     (loc_942).l
ROM:0000036A ; ----------------------------------------------------------------------

Hmmm. Nice subroutine calling.

As for:

Code: Select all

ROM:000003D8 aHeySendAMessag:dc.b '   Hey, send a message to tmeeco3@hot.ee !!!   ',0
ROM:0000062A aIfYouDoICanSen:dc.b ' If you do, I can send you te source of this POS :P  ',0

I already got all what I need. This is not so big code.
PS I guess you used assembler to control everything?
PPS Sorry for that brutal method of getting info. %)

I try hide fun stuff into my ROMs, but sometimes I forget about it :/

POS indeed means Piece of $h1T

Also, you forgot "your ad here" in the phone number, which I saw in a QB raycaster game on a wall

Hmmm. Nice subroutine calling.

it is faster, and quite nice optimization in code where some routines get called very frequently

Yeah, it is all written in assembly, assembled with SNASM68K

np with the code extraction method

I made a smaller version of this a while ago

http://minigamecomp.org.uk
Games 2009, scroll all the way down.

Direct link (hopefully works) :
http://minigamecomp.org.uk//minigamecom ... r/PONG.zip

I could have made it smaller but I did not want to throw out all texts etc.
