- +Compact.s/UnPack : Fixed issue that sometimes makes screen palette not correctly updated when unpack screen using more than 32 colors.
- +Lib.s/InGetIcon? : Get Icon now stores up to 256 colors icons palette.
- +Lib.s/InGetIconPalette? : Get Icon Palette now restore up to 256 colors.

- +Compact.s/SPack : Memory corruption issue fixed
- Commands/Help for informations about SPack & UnPack improvements/Changes and compatibilities with older AMOS Professional versions.
- Renamed AMOS.library to AmosPro_AGA.library to allow both old Amos Professional ( with AMOS.library) and new Amos Professional AGA version (with AmosPro_AGA.library) to run on the same computer without conflicting.
- +Compact.s/Unpack compatibility with old ECS Packed pictures/Screen is now retablished when AGA is also supported.
It's just a variant of the existing command : SPack ScreenID To BankID, Left, Top, Right, Bottom
I found the order more logical when entering screen coordinate after ScreenID and before BankID.
Due to that insert in the compat.lib, Unpack commands will not be recognized and must be updated inside existing AMOS Professional source code (.AMOS Files).
I have found a simple solution to make SPack & Unpack works for both ECS and AGA configuration.
Here is how it work.
Whatever the configuration you run the program, SPack will store 256 colors in the image. It's better this way as the AMOS structure to handle header is well fixed and there is no risk to override area.
When you Unpack picture, it will firstly consider it's a 256 colors registers sized (even with 32 colors, simply that others colors will be rgb(0,0,0).). If header is not found witht eh PsLong AGA size (for 256 colors), it will go back and check the header at PsLong ECS size (for 32 colors).
With this you can pack unpack picture created with AMOS Professional AGA.
But you can also Unpack pictures created with older AMOS Professional.
As an additional notes, Pictures/Screens packed with AMOS Professional AGA will not be compatible with older AMOS Professional versions.
I Plan to rename AMOS.Library to AmosAGA.library to be sure that an AMOS Professional AGA program will never be run with an older AMOS.Library version.
Due to the fact that AMOS Professional uses fixed size structures, I encounter a problem I must resolve to makes some commands being compatible with old AMOS Professional's datas, and new ones. It's the case of the SPack and Unpack methods.
in the +Equ.s file, AMOS Professional define this small structure for the bitmap compression header :
; BITMAP PACKER/UNPACKER
; Packed screen header
PsCode rs.l 1
PsTx rs.w 1
PsTy rs.w 1
PsAWx rs.w 1
PsAWy rs.w 1
PsAWTx rs.w 1
PsAWTy rs.w 1
PsAVx rs.w 1
PsAVy rs.w 1
PsCon0 rs.w 1
PsNbCol rs.w 1
PsNPlan rs.w 1
PsPal rs.w 32
PsLong equ __RS
SCCode equ $12031990
- The pointer PsPal will store 32 colors in a total of 32 words.
- The constant PsLong define the total length of the structure.
If I want to add support for AGA 256 colors, I wll have to makes PsPal become : PsPal rs.w 256.
This mean that this structure will be longer.
It result in an incompatibility issue with bitmap packed with previous versions of AMOS Professional as to Unpack it uses PsLong to shift to area to decompress...
I tried to define it dynamically. Files are correctly created but AMOS Professional return "It's not a packet bitmap".
There are some other places where data are stored with a fixed size. THis mean that I will probably have to make a choice.
- Create a new Packing/Unpacking set of methods that will be incompatible with older, and leave older for compatibility (should takes more time).
- Update the new Packing/Unpacking method to directly handle at max 256 colors in a static size way (always store area with 256 colors, like amos did previously with static size of 32 colors even for screen with smaller depth.
This choice will have an impact on compatibility and way of coding under AMOS.
By re-opening the project, I have also re-opened the previous <<to do list>> with both my ideas and ideas from AmosPRO users.
Here is the current list :
- Screen open add ECS:1024x1024 limit, AGA:2048x2048 limit
- Check Pack/Unpack color count te retrieve compatibility with ECS packing
- Makes BOB/Sprite get to get the true amount of color and makes Get Color Palette restore the correct amount.
- Add AGA 24 bits color support in copper list
- Add AGA 24 bits color support in load IFF / IFF Anim system
- Add support to change sprites color palette index.
- Update demo to use SCREEN HIDE/SHOW to now display IFF/ILBM loading times.
- Add internal checking to avoid loading/writing outside of memory banks (Load Frame, etc.)
- (WIP) I plan to add in next update a "Use Screen Palette" to switch AGA Palette between screen own aga palette.
- Screen open resolution up to 4096x4096 pixels (Vampire users)
- Increase the AMAL system limits up to 16 channels
- Increase the BOBS amount limits up to 64 bobs
- Increase the RAIBOWS system limits up to 4 rainbows
- Update the Object Editor to handle 256 colors
- Update the Sample Editor ( ??? )
- Integrate a faster BOB system (like PowerBobx)
- More dual Parallax modes.
- Integrate a faster Icons tile system (Turbo ? Personal ? ones)
- Implement WAV audio playing (Datatypes ?)
- Support GIF animations
- Support more graphics format for Images loading (jpg, png, bmp, gif, etc. Datatypes ?)
- Import TMX tiled maps (From Windows)
- Add an auto .ASCII save when saving .AMOS files (check if a flag (button, option) can be added in configuration to enable/disable this feature).
If you have ideas or improvements you'd like to see in Amos Professional AGA, feel free to send it using the Contact form available from the menu.
The first new will contain the detailled changes made to François Lionet's AMOS Professional Official Source Code to add AGA Support :
With the huge amount of works already done, I consider that it enter directly in the case of MIT Licence saying : "Licensed works, modifications, and larger works may be distributed under different terms and without source code."
Some other reasons are also linked to the choice to release only binaries at this moment.
Source code will be released ... Later. When everything will be finished.
