Try using sleep mode and waking up, that might fix the wifi.

I fail to see what that nintendo DS game has to do with bike theft.

Tried softy?

This is something I've never quite understood. Why do people make such a big deal about Galaga, and smother it with rave reviews when referring to 80's arcade games?

Are you talking about that "Offsets per tile mode" thing which drives Tetris Attack?

I got a K: drive, just because I repartitioned my drive after installing Daemon Tools (with 3 fake CD drives), and had 2 USB devices plugged in.

I highly doubt that, BG3 is 4 colors only.

I think you need Firefox and IE7 for this to work.

Oh noes! The archives are missing.

I've just finished creating an exact clone of the Atari 2600 game "Adventure" in flash!
Go to http://www.dwedit.org/adventure/ to play the Wii-Friendly version, or http://www.newgrounds.com/portal/view/391061 where it got a really crappy score.

And when I say exact clone, I mean exact clone. As in "I used a disassembly".

And firefox has finally been updated to fix this hole.

I'm just wondering if you could split the computing board into a programming part, that's the only major thing I miss from the old Acmlmboard. ||board has it split, nobody posts there since there is no intelligent life on ||board.

Are you sure it's running faster? It has a timer system to ensure the game runs at 60 frames per second, no matter how crappy your CPU or Browser is. If you are used to PAL speed of 50FPS, then yes, 60FPS is faster.

And no, it's not "Pretty accurate", it's exact. Only difference is that it does not simulate the bridge sprite wraparound when the bridge is placed on the right edge of the screen.

I sure hope this isn't anything at all like your last hack

I wonder if you finally decided to rearrange the linkage of rooms in the palaces...

I'm looking at that screenshot of the Forest Palace. It looks like that stalfos is about to take a very hot bath. But if that stalfos was placed further to the left, and Link did not have the downward thrust, then that would be frustration city.

First, the text file describing how to expand the rom:

First, you need to physically expand the rom.
Duplicate the first 128k after the NES header, then change the header to indicate that the PRG size is now $10 instead of $08.

Then make these changes to allow the game to use the expansion:


Paste this code into FF64 (3FF74)
	A9 00     LDA #$00
	8D FE 7F  STA $7FFE
	8D FF 7F  STA $7FFF
	4C 70 FF  JMP $FF70

Modify reset vector at FFFC (4000C)
 replace this:
  70 FF
 with this:
  64 FF


Paste this code into FF4C (3FF5C)
	4A        LSR
	4A        LSR
	48        PHA
	29 08     AND #$08
	8D FE 7F  STA $7FFE
	68        PLA
	29 07     AND #$07
	60        RTS

Go to CBA6 (3CBB6)
 Replce this:
  4A        LSR
  4A        LSR
  29 07     AND #$07
 With this:
  20 4C FF  JSR $FF4C
  EA        NOP

Paste this code into FF58 (3FF68)
	8D 69 07  STA $0769 
	48        PHA
	AD FE 7F  LDA $7FFE 
	8D FF 7F  STA $7FFF 
	68        PLA
	60        RTS

Go to CD59 (3CD69)
 Replace this:
  8D 69 07  STA $0769
 with this:
  20 58 FF  JSR $FF58

Replace the bankswitching code at FFC5 (3FFD5) with this:
	A9 00     LDA #$00
	F0 06     BEQ $FFCF
	AD 69 07  LDA $0769
	0D FF 7F  ORA $7FFF
	8D 00 E0  STA $E000
	4A        LSR
	8D 00 E0  STA $E000
	4A        LSR
	8D 00 E0  STA $E000
	4A        LSR
	8D 00 E0  STA $E000
	4A        LSR
	8D 00 E0  STA $E000
	60        RTS

And the obligatory "Example of how to use the expansion" post:

Okay, here's an ASM hack that allows you to expand Zelda 2.
Read the text file, zelda2_expand.txt.

Also read the overworld locations table format text file, zelda2_overwold.txt, so you know what the hell I mean when I say "W" byte.

The ASM hack allows you to specify that an exit to an overworld/town/palace is on the second 128k.
You do that by setting bit $20 of the "W" byte.
LIMITATIONS:
When you leave a palace or town located on the second 128k, you will go back to an overworld on the second 128k, even if the teleporter that took you there was on the first 128k.
You also need to specify the $20 bit for ALL towns and palaces you want to place on the second 128k, otherwise they will switch back to the first 128k.
When you continue or restore from a save, you start on that half of the rom.

Example!

An example of using the expanded rom:
First expand the rom and apply the asm hacks
Then copy 4000 bytes at 8010 [file address] to 24010.

Let's change that forest with the 50 point P bag to another overworld.

Hack these bytes:
4631: AA
46AF: 00
46EE: 20

After doing all the hacking, that forest now takes you to a messed-up version of the second overworld (because we copied that rom bank from 8010 to 24010).

Possible hack ideas: (use your imagination!)
Double the width of the overworld maps by having caves link the two halves together.
Make huge palaces, now that you have twice as much room as before.
Have a light world/dark world. Note that palaces share RAM areas to store their state, so you could put the key in one world, and the locked door in the other.
Have a Palace that you enter in such a way that is hard to exit from, then when you clear it, you emerge on the second world.

If you want to map out the SRAM, I'd say write DEADBEEF repeatedly across the SRAM area, then create 3 new saves, then play through the game. Whatever stays as DEADBEEF is probably free SRAM.
