We need a list of every library fuction, and exactly what it does.
Example:
directin
Is a direct input routine.
inputs:
a = key group
outputs:
z=No key pressed
a=key code
I went to the developers section of http://detachedsolutions.com and pulled up a list, but I do not think it is complete.
What we need is a list of every possible MirageOS routine and exactly what it does, its inputs, its out puts, destroyed registers et cetera...
Why do we need them you may ask. Simple, since the MirageOS souce is unavalable, our only chance to make NimbusOS run MirageOS programs is to write identical MirageOS libraries! This is why we need to know exactly what we need, so we can code it.
For example, directin would be very easy to code.
clone_directin:
push bc
ld b,a
ld a,0FFh
out (1),a
ld a,b
out (1),a
in a,(1)
pop bc
ret
You see, I do not know if it is okay to destroy register b, so I peserved it because if it was destroyed, preserving it won't hurt, but if not, it would be an error.
Now, somewhere within nimbus, we would have MirageOS vectors.
directin:
jp clone_directin
...
Why would we have this you may ask. Simple, so we can put clone_directin anywhere we want within NimbusOS and programs will still be able to find it without being recompiled.
Obviously, we will also need to know where MirageOS puts directin, so we can hae our table in the correct place.
Pleae make a list of all the MirageOS library routines. |

Let us make a collection of Mirage libs. On a post.
directin
Code:
directin:
push bc
ld b,a
ld a,0FFh
out (1),a
ld a,b
out (1),a
in a,(1)
pop bc
ret

If you don't want to code the whole thing, why not dissasemble the mirageos program and find the libraries?
Also, I would like to help with the libraries. As you might know, I am working on my own shell that works like a computer. I would like the libs too. |

Don't you think he tried that already? JBirk is not and idiot. There's obviously something they don't want him to know, otherwise we wouldn't be having this disscussion.

I can't get my disassembler to work correctly, which one are you guys using?  I could be of help! |

Actually, I'm not quite the idiot you think I am. If you weren't so quick to judge...
Most people would NOT think of asking for the source. I know some of the Detacheds guys, and like I said, if you explained that you want the source to the libraries for compatibility, I'd be surprised if they turned you down. There's a difference between code from a disassembler and the original source. |

Asking for closed-source code without even saying why? Who does that? Most people do think to ask for the source first, why? Because it's the easiest way to get it. You think people want to disassemble MirageOS? You know how much complicated code that is?
Arcane: you are correct. |

Well, no duh, genius, of course, that's the whole reason I brought it up.  And I never said no reason:

I think what he tried to say is that JBirk did ask for the source, and when he did he probably explained what he wanted it for.
It wouldn't hurt to ask one more time though. Since you know some of the Detacheds guys, how about you ask?
Also, why would someone not think about asking for a source? that's the easiest thing to do right?? |

Well, I use the term "know" loosley. I think I "know" "them" well enough that they'd be OK with it. I mean, why not just give you the source (after all it's just the libraries), they're gonna be in the shell either way, whether from the original source or a disassembler.
I "know" Michael Vincent and Dan Englender from hanging out on #tcpa on EFNet. Michael wasn't at all involved in MirageOS (He's not one of the original members from the TCPA). Dan whoever, did a lot of the coding for MirageOS. I will try to see if I can contact with him. Can't make any guarentees, though.  |

Any update on how the it's going?

| You could also go into calcsys, go to the part of the mirage source code with the jump table (the addresses of the routines are in mirage.inc) and read the source there. It's kind of hard to understand through calcsys though. |

i can get a full disassembly though.
example:
Code:
;BOOTCODE START
4000:3E77:LD A,77h
4002:D304:OUT (04h),A
4004:3E7F:LD A,7Fh
4006:D306:OUT (06h),A
4008:3E03:LD A,03h
400A:D30E:OUT (0Eh),A
400C:C3D580:JP 80D5h
400F:312E30:LD SP,302Eh
4012:3000:JR NC,4014h
4014:FF:RST 38H
4015:FF:RST 38H
4016:FF:RST 38H
4017:FF:RST 38H
4018:AA:XOR D
4019:64:LD H,H
401A:7F:LD A,A
401B:FA677F:JP M,7F67h
401E:CB6B7F:BIT 5,D
4020:7F:LD A,A
4021:CA4B7F:JP Z,7F4Bh
4024:5E:LD E,(HL)
4025:4B:LD C,E
4026:7F:LD A,A
4027:87:ADD A,A
4028:4C:LD C,H
4029:7F:LD A,A
402A:D5:PUSH DE
402B:4C:LD C,H
402C:7F:LD A,A
402D:76:HALT
like that.
Address:opcode:disassembled instruction
not sure if my friend gave me a copy of the disassembler, will check tho. else we'll have to wait until he gets online.
