- A new RAM CALL allows you to know which ROM version your program is
running on. Use it this way:
move.w #ROM_VERSION,d0
|------------------------------------------------|
| ROM_VERSION values | Corresponding ROM Version |
|------------------------------------------------|
| $1100 | 92+ 1.00 |
| $0100 | 89 1.00 |
| $1101 | 92+ 1.01 |
| $0105 | 89 1.05 |
| $1105 | 92+ 1.05 |
| $0201 | 89 2.01 |
| $1201 | 92+ 2.01 |
| $0203 | 89 2.03 |
| $1203 | 92+ 2.03 |
| $0000 | UNKNOWN 89 |
| $1000 | UNKNOWN 92+ |

- Due to the need for compatibility with the new ROM versions, a few things have changed.
YOU MUST PORT YOUR PROGRAMS TO MAKE THEM WORK WITH ALL ROM VERSIONS (see below).
- A new RAM CALL allows you to know which ROM version your program is running on. Use it this way:
move.w #ROM_VERSION,d0
|------------------------------------------------|
| ROM_VERSION values | Corresponding ROM Version |
|------------------------------------------------|
| $1100 | 92+ 1.00 |
| $0100 | 89 1.00 |
| $1101 | 92+ 1.01 |
| $0105 | 89 1.05 |
| $1105 | 92+ 1.05 |
| $0201 | 89 2.01 |
| $1201 | 92+ 2.01 |
| $0203 | 89 2.03 |
| $1203 | 92+ 2.03 |
| $0000 | UNKNOWN 89 |
| $1000 | UNKNOWN 92+ |

- The doorsos::kb_vars and doorsos::Heap variables are now RAM CALLS, ie. managed by the kernel.
- Since the handle of the folder list and of the 'main' folder changed in the new ROM, they are now RAM CALLS too. To use them, do the following:
move.w #doorsos::FolderListHandle,d0 ; Don't forget the '#' before !
and
move.w #doorsos::MainHandle,d0
------------------------------
| PLEASE PORT YOUR PROGRAMS !! |
------------------------------
Please take the time to port your programs ! There is very few to do, and when done your program will be compatible with all ROM versions. Here is how to make your program compatible
- Don't use any direct RAM address.
- If you use doorsos::Heap, doorsos::kb_vars, you have to recompile using the new DoorsOS.h from this package.
- Please replace any use of $8 and $9 as handle of (respectively) the folder list and the main folder:
move.w #$8,d0 ; d0 = handle of the folder list
move.w #$9,d1 ; d1 = handle of the main folder
will be replaced by:
move.w #doorsos::FolderListHandle,d0 ; same as before, but it will
move.w #doorsos::MainHandle,d0 ; work on ALL ROM versions
- That's all you have to do ! :-)
