Due to many changes in code is possible to have some unnoticed bugs.

Please comments.

The objects of this version can be easily ported to Sonic 3/K.
Here a prototype of next generation of Sonic Delta: (Gens only 40Mbit Rom)

Esrael Neto Assembler Editor

Whats New?

- Support to bat file added through directive compiler in Project File
- Sonic 1 and Sonic 2 Art And Level compression format added into compressor and decompressor. (Bit perfect in compression).
For Sonic 1 Level RLE compressed size is only required if you are decompressing from ROM.
For Sonic 2 Level the decompressor can detect end of compressed data ($FF $FF $00 - Flag).
- Hex debug can save files now.
- Hex debug can display strings using custom fonts.
- Search added to hex debug and are based on selected font. Ex: You can load a Sonic 1 Font and Search for GREEN HILL to find Level Select Menu.
- Tile Editor can edit SMS uncompressed files, Sonic 1 SMS compressed Art and Sonic 2 SMS compressed Art. Tiles can be saved to bmp files for use with Sonic Series Level Layout Editor.

Sonic Series Level Layout Editor.
- Sonic 2 SMS support added.

Sonic 2 SMS With Project File
If you open Sonic_2_SMS.epr using "Open Project" The complier Directive inside will override the editor options.


Fixed some bugs in Internal M68k / Z80 compiler.
Other Fixes

Old projects (loading asm file as project) are compatible with this version.
New projects require Session [Assembler] inside epr file ex:

[Assembler]
begin
Main = src\s2.asm
Compiler = build.bat
end;



Enjoy....

Bugs. Please Comments.

Sorry if was done before, but I don't find it in forums.

If you pay attention after defeating some bosses in Sonic 2 you will notice some strange things.
I am not good in explanations. But look in to pictures to understand what I am saying.

Edit:
When the boss is defeated, it falls apart. If it is facing left, it falls apart properly. However, if it is facing the other way, the pieces still fall as if it was facing the other way. This behaviour is obviously wrong. The following code checks which way he is facing, and properly calls for the right routine so that he falls apart properly!
Thanks to Irixion for better explanation:

Using Sonic 2 Delta for comparisons.

(All codes translated to use with Xenowhirl, 2007 version.)

Original Topic of pre-release ->Delta v0.24 preview

This version is not the same base (Sonic 2 rev 2 used here) as preview, but the same idea was used here with new features:

- Title Screen is now animated (Sonic 2 Final with Sonic 2 Beta).
- Sonic Object from Sonic 2 Final.
- 7 emeralds, which now enable Super Knuckles, Miles e Sonic.
- Sonic 2 Final Ending sequence with Sonic 1 Credits.
- Sonic 1 Special Stage as Bonus Stage through LampPost with 50 rings.
- HUD added in Bonus Stage
- Sonic 2 Special Stage can be acessed like previews versions (Big Ring at end of levels with 50 rings).
- Sonic 3 Title Cards style.
- New Boss Meter HUD
- Edited Sprites for Sonic 1 Levels to be compatible with Super Sonic / Knuckles / Miles.
- Alpha Levels reused for EHz and HTz.
- Custom Sonic 2 Beta Sound Driver with Two life Sounds one for Sonic / Miles and other for Knuckles.
- Invencibility and Super Sound are player especific

A lot of bug fixed:
- Infinite Title Screen scrolling now works perfect while Sound Test is highlighted.
- Illegal Instructions in Sonic 1 Levels
- Colisions in Sonic 1 Levels
- Fixed some undocumented bugs while defeating Boss Like ARz, CNz and MCz Boss.

Tested and fixed to work in Real Genesis / Mega Drive.
Invalid Addressing like move.w #$0000, (FE11).w works on emulator, but crashs In Real Hardware.
Invalid Pointers ignored by emulator, but crashs in Real Hardware.

If you played and found bugs please comments.

Edit: New build with fixes (v0.24a)

This is a new program which I am working.

This program has support for MP3 / WMA and other formats using windows codecs, and has two internal codecs one for reading VGM / VGZ and other for CDDA.

The program look likes an older tape deck with analog VU Meters. The needle position was mapped to represent real dB samples in two modes Peak Level and RMS. (Only in Big VU).

You can choose other visuals which includes, Digital (Peak Level and RMS simultaneous), spectral and Oscilloscope. You can open files using the button "LIST/INSERT" on remote control or in Button Eject in The Tape Deck or in "Menu Playlist -> Adicionar a playlist..." Drag and drop files will work too.


English version of menus will be added.
