I did a speedrun of this game shortly after it was released and the game wasn't as bad as I thought it would be for being a kids anime/cartoon show. It'll be a bit longer then the last two games I worked on, plus the battle system is a bit on the inconsistent side (especially for Aang). I'll put up what I have now just to see what people think - if it's worth continuing. WIP 1 Complete through the 1st chapter. In-Game Time: 0:03

Hmm, too bad you can't run in this game, it seems too slow paced otherwise. But I'll watch the finished product if you get there. I wonder if the second game would feel faster though...

I played through a bit of this game and noticed that either it has horrible lagging issues (especially in multi-enemy battle zones) or my computer can't keep up with the emulation, though I expect it's more likely the prior. I wonder if that lag can be avoided at all, other than the obvious kill enemies quickly. Perhaps the lag doesn't kick in until an enemy is active (due to proximity)...

Nice link to a rather obvious and well-known speedrun site/community.

Avatar was the first game chosen for me to try and understand Lua scripting and Hex editing to figure out memory address values. Although I do not have much interest in TASing this game anymore, I do want to share my values and lua script.
Make sure when searching that you are looking in EWRAM for memory domain.
006F4C	0	0	EWRAM	Camera PosX
006F50	0	0	EWRAM	Camera PosY
0032C8	0	0	EWRAM	Screen Pos X
0032CC	0	0	EWRAM	Screen Pos Y
0032BC	0	0	EWRAM	Screen PosY Offset
0032B8	0	0	EWRAM	Screen PosX Offset
003144	0	0	EWRAM	Sokka Selected
00318C	0	0	EWRAM	Aang Selected
003154	0	0	EWRAM	Sokka's Energy
003150	0	0	EWRAM	Sokka Stance
018700	0	0	EWRAM	Possible EnemyID
018704	0	0	EWRAM	Enemy Type (22 is sword guys, 47 is archer)
018778	0	0	EWRAM	Enemy Stance (1 is standing still, 513 when chasing you, 10** when attacking)
0187C8	0	0	EWRAM	Enemy Counter (resets to 0 when animations happen)
018710	0	0	EWRAM	Enemy PosY
01870C	0	0	EWRAM	Enemy PosX
01C134	0	0	EWRAM	First Archer Enemy
0177CC	0	0	EWRAM	Aang Map X Coords
0177D0	0	0	EWRAM	Aang Map Y Coords
01790C	0	0	EWRAM	Sokka Map X Coords
017910	0	0	EWRAM	Sokka Map Y Coords
0187A4	0	0	EWRAM	X offset between enemy and player?
0187A6	0	0	EWRAM	Y offset between enemy and player?
Most of these values are 4Byte Signed, but occasionally some are 2Byte. Dunno if that really matters or not.. Camera Position -> moves only until end of backgrounds On-Screen Pos + Offset -> moves all over screen, when camera is moving player stays in center Saka Stance -> only two stances, 1 = attacking, 255 not attacking EnemyID: This one is kind of tricky, but there are two 2Byte values next to each other (and right before EnemyType). All their position and offset between player and enemy, as well as their counter and stance are located in these chunks. For the first like 5 swordsmen it should be 0001 0000, 0001 0001, 0001 0002, etc. If I were to continue my lua script, I would try to figure out a way to just set the enemyID's and Types and ahve the lua script do the rest of the work to figure out stance, counters, position, because swordsmen and archers addresses are located the same distance from their enemyIDs. Map coords: These are a pain bacause it's different for each screen to get the position of enemies and sokka and aang. I was trying to find other values that would work but no dice.
local ScreenPosX = 0x32C8;
local ScreenPosY = 0x32CC;
local XOffset = 0x32B8;
local YOffset = 0x32BC;
local Saka = 0x3144;

while true do
	memory.usememorydomain("EWRAM");
	PosX=memory.read_s32_le(ScreenPosX)-memory.read_s32_le(XOffset);
	PosY=memory.read_s32_le(ScreenPosY)-memory.read_s32_le(YOffset);

	gui.drawText(5,200, "Pos X:" .. PosX);
	gui.drawText(5,220, "Pos Y:" .. PosY);


if memory.read_s32_le(Saka) == 1 then
	if memory.read_u8(0x3150) == 255 then
		gui.drawEllipse(PosX-32, PosY-30, 67, 58, "Red");
		else
		end
	else
	end

	emu.frameadvance();
end

Looks good, solarplex! Just curious, but where did most of the time savings over the old run come from? Better firebender fights? I also created an entry for this game in the Game Select in case you want to post WIPs for this game.

Link to video video processing. Very hard to compare but you can see vba-rr gets insane with the lag frames more so than BizHawk. So I would say either its better emulation or im just a magician with causing 400 less lag frames out of nowhere.

Ohh, emulation differences, of course. BizHawk emulates the BIOS, while VBA doesn't, so it probably is better emulation reducing all that lag.

There are also other emulation differences between the two GBA cores, and Bizhawk's is not necessarily more accurate.

Link to video Im starting over after this one, its better to have toggling on instead of changing between characters each time.

Link to video redone from frame 10,000(ish) to enable character toggle which holds the same character through a level's areas. Also fixed a bunch of laggy areas.

Found a dumb glitch during my casual playthrough which lead to a more major skip... https://www.youtube.com/watch?v=z9CU5fPBRGY https://www.youtube.com/watch?v=r0Adqg3l48U No exact idea how to do it, but it's rather precise. Don't really like how the game has dynamic memory and I suck at finding pointers. Also sucks solarplex has gone missing.

That boss skip is pretty damn amazing.
