Thanks for your feedback... I updated the script, see: https://gist.github.com/jedie/22dba94f5b7534f946f9/revisions Changed MP to MS and now $4F, $51 and $53 moved via X The result is the same :( $83E0 seem to be to EXP and most significant mantissa part representing 0.111*2^3 = 7, isn't it? I suspe...

Playing with the trace filter, i get the complete trace of the test program. From machine code call $4000 until RTS: https://gist.github.com/jedie/4c884924d6a4e393f4c9 I have input the value 2... I searched for all ST ops and see that there addresses used to store things are only: 4f 50 51 52 54 63 ...

I try my new filter stuff to analyse the xroar trace... Get this, e.g.: ... [Skip 21546 lines] ... 4003| bd8c37 JSR $8c37 cc=a0 a=00 b=06 dp=00 x=4000 y=890b u=0000 s=7f1f | $4003: UNKNOWN ... [Skip 78 lines] ... 4006| 9e4f LDX <$4f cc=88 a=00 b=0d dp=00 x=83c0 y=890b u=0000 s=7f21 | $4006: UNKNOWN ...

I tried a other variant, see: https://gist.github.com/jedie/22dba94f5 ... /revisions

Load D from $1052 call "Add D to FPA0" and then use Reg X for transfer the FPA0 values to $70xx

But same result as many other variants: Only the first Value (the FPA0 exponent) will increased by **2

Damn!!! I used all the time the "D32 Enhanced ROM v2.2 by Stephen J. Woolham" and not the origin

I retested all reversions from https://gist.github.com/jedie/22dba94f5 ... /revisions with the origin ROM and with JSR $9C3E and JSR $8C37 but also with unsatisfying results...

This is fixed, by deactivating "3D acceleration" in VirtualBox

I hacked a script that used the "ROM Info file" from: https://github.com/6809/rom-info

See: viewtopic.php?f=8&t=4889&p=11422#p11422

Add the ROM info into a existing disassembled ROM file, is also made quick...

Add a second script that add address information into the trace. Use the ROM Info file from: https://github.com/6809/rom-info e.g.: xroar -trace | python add_info_in_trace.py --infofile Dragon32.txt or better: Combine both scripts: $ xroar -trace | python filter_xroar_trace.py --loop-filter startup_...

@Stew: I will extract address+comment from your files here and add them to https://github.com/6809/rom-info ... I hope you are not against it. With a hacked script (see: https://gist.github.com/jedie/356d51afc2a84bef4f19 ) i created https://github.com/6809/rom-info/blob/master/ROM%20Addresses/Drago...

Again the Questions: Why are the UNRAVELLED Books exist from the CoCo ROM? IMHO they contain the complete ROM, isn't it? Are they not official? Illegal? I updated the Makefile so that it works with lwasm from LWTOOLS. I confirmed it builds a 100% identical Dragon 32 ROM image. (Make file attached he...
