When you go to edit individual enemies you will proably see something like 0D FF 00 00 04 A8 00 8F. It's set out as enemy type, respawn, diffucalty, x position and y position. So, 0D is the enemy type, FF is whether it respawns, 00 00 is the difficulty and 04 A8 00 8F is the position. To change the difficulty you will have to change the 00 00 to 00 01 or 00 02. The 

It worked perfectly, thanks. I Wonder now how to add other enemies in "Ble Lake Woods" or this level only works with dragons? I was thinking of putting tanks, ( However i do not know the HEX decimal number that i use ).

Yes, you can change the enemy types in any level. When you go to the top of the enemy information of a level, you will see that there are 2 or 3 slots for enemies. In Blue Lake Woods I there is only two. The first one is 00 0C, which means dragon with the 1st colour palette, and the second one is FF FF, which is empty. The reason for this is dragons take up two spaces (flying and walking). Tanks also take up 2 spaces and Lions take up 3. 

So, to change the dragons to tanks you would change 00 0C to 00 0A. Then at the begenning of the information for each individual enemy, you change the enemy type. For example, 0D FF 00 00 04 A8 00 8F would change to 0A FF 00 00 04 A8 00 8F. 

It is possible to add two enemy types to Blue Lake Woods I as long as you choose two enemies that take up one space. For this example, let's use Hopping Skulls (1D) and Mini Hopping Skulls (1C). You would change the first enemy slot from 00 0C to 00 1D. Then you would change the second slot from FF FF to 00 1C. Then, of course, you would change the individual enemy information accordingly.

Here are the hex codes for each of the enemies:

00 = Fire

01 = Crystal

03 = Alien

04 = Armadillo

05 = Tar Monstar

06 = Ball

07 = Archer

08 = Orca

09 = Crab 

0A = Tank

0B = Shooting Tank

0C = Flying Dragon

0D = Dragon

0E - Cloud

0F = UFO

10 = Goat

11 = Ninga

12 = Lion

13 = Scorpian

14 = Twins

16 = Drip

17 = Hand

18 = Tornado

19 = Fire

1A = Drill

1B = Emo Rock

1C = Mini Hopping Skull

1D = Hopping Skull

20 = Heady Metal

21 = Boss' Eye

22 = Shishkaboss

23 = Boomerang Bosses

24 = Bagel Brothers

It Worked, Thanks again. Sorry for asking so many question, hope i'm not bothering you. to finish my doubts: the level "Blue Lake Woods 1" has four enimies ( 4 green dragons ), is i increase with value to 8 or more dragons?

No problem.

After the last enemy type slot there will be a cell before the individual enemy info starts, which in Blue Lake Woods reads "04" which means this level has 4 enemys. To increase/decrease the all y ou have to do is change this number and then add or remove enemy information from the end. However, the number must be in hex decimal number. For example "10" would not equal 10 enemies, it would equal 16 enemies because after 09, it obviasly goes 0A, 0B. etc. 

Thanks man, how could i do to enimies so that they die, the be reborn? Example: 0A "FF" 00 00 XX YY. What should i do with FF?

Is has been a while but if I believe that is the so called flag FF will kill it permanently, 01 might be re-spawn, there are also enemies with 00 something you have to try out to find out.

thanks man, i will test here.

Just thought I'd let you all know. That mod I was working on, I've started working on it again under the name Kid Chameleon: Appson Aid and have made a thread of the forum about it. I've put a download link on there and if you've got any comments or suggestions I would love to hear them.

There was actually a lot of discussion about your mod earlier today. Once I get some other things done I'm going to post my own thoughts on your page.
