Aha so you got there faster than me, thank you. I was automating this change on ML_display_vram(). Unfortunately this is not enough yet, this version of Jetpack kinda works but really doesn't. The display is shifted suspiciously to the bottom, and there are a lot of visual artifacts. Turning the calc (screen) on and off restores the parameters but this is definitely not usable.
Jetpack's code might use other direct-DD functions, I'll keep looking into that.

ML_clear_vram() and ML_pixel() are irrelevant here, they don't use the DD.
You seem to have missed ML_set_contrast() and ML_get_contrast() at 8f9a and 8fa6. I disabled both by removing every access to the display registers, which solves the contrast issue for the title screen only. Still contrast issues everywhere else and every frame is displayed starting at row 4 so 4 rows at the top still display the main menu and 4 rows of Jetpack Joyride are invisible.
There seems to be no reference to the second occurrence indeed.
I have confirmed that the modified ML source works on the Graph 35+E II when compiled with GCC. So it must be specific to the SDK setup or Jetpack itself.

I totally didn't see the ML_set_contrast() and ML_set_contrast()
I recognized that part of the code wasn't from ML_display_vram(), but I just didn't think anything about it
I must have been too tired
I still don't get why changing 008f74 220b or r0, r2 to 008f74 320c add r0, r2 would fix anything
The max r0 could be is 0x3F which when ORed or ADDed with 0xFFFFFF80 should result with 0xFFFFFFBF (0xFFFFFFF with 0xFFFFFC0) which doesn't cause any overflow
I did forget about changing 008f6e 6013 mov r1, r0 to 008f6e e000 mov #h'0, r0.
Which was the reason for the screen not displaying anything on the top 4 rows
Citer : Posté le 13/09/2020 08:40 | #
Thanks for your analysis. I also don't see why any of these statements have an effect. mov #0, r0 is the same as mov r1, r0 since r1 is initialized to 0 in the same basic block two instructions above. And as you mentioned, or and and are identical here.
(Actually both modifications result from an attempt from me to count rows from 0x7c up instead of from 0x80 up. In this situation the add makes sense. It worked, but omitted four rows on top, so I put mov #0, r0 again and this time it worked normally. I don't know yet why r1=4 initially.)
Also the flickering on the screen was due to the 4 extra rows at the bottom, I confirmed that setting the limit from 64 to anything smaller than 60 (while keeping the offset problem) solved that part. Maybe that extra RAM is used for other settings or whatever.

Which caused the offset by 4 bug
Aaah I got pwned by my own modification of the code and did not even realize it. Thank you for spotting it. xD
Now let's work on automating all of this. I would like to have two levels of compatibility:
• Binary compatibility: for add-ins which provide the source code, rebuild with a compatible version of MonochromeLib (detect GIII by OS version major number = 3) and continue shipping a single binary for all SH4 platforms.
• Binary edition: for add-ins which don't provide the source code, automate the detection of MonochromeLib functions and rewrite them. Ship an additional binary for GIII models only.
Because compiled MonochromeLib functions have references to PC-relative data and the offsets depend on how many MonochromeLib functions are compiled in, it won't be possible to detect a constant byte sequence, and that wouldn't be robust either. I'm considering using my fxos disassembler which does the binary work for us, though it will required some work.
If possible, it would be best to start by porting add-ins that have source code.

Since @Moutaindew asked for doom in Installer et jouer à des jeux de type add-in sur une graph 35+ e II
I very quickly made a (possibly*) compatible Graph 35+eII Wolfenstein 3D Addin: Wolfenst.g1a
Based on the SH4 download (2nd link)
(oops. deleted my post by mistake)
But it was not in vain!
As I take this opportunity to reupload the file (but with modifcation): Wolfenst.g1a
I took a guess as to why it still wasn't working and I think I've found the problem! (It just looks like the possibility of automating this keeps getting harder and harder)

Citer : Posté le 21/09/2020 12:06 | #
Your port mostly works now Redcmd, thank you! I checked your file, I see you removed the reg=1, data=1 command which sets increment mode. As we discussed earlier this command is indeed no longer used in the new driver.
I can now start the add-in and play the game, although pressing EXIT during a stage crashes the calculator. I have checked that the crash also occurs with the currently-available SH4 download on my Graph 75+E. This is thus a completely different bug, so your version is indeed a port of the current version for the Graph 35+E II.
I added the file to the game's page with credit. Thanks!

J'ai contacté l'auteur, c'est un add-in gint donc c'est compatible au même titre que Terrario - il devrait suffire de recompiler le programme avec la version corrigée de gint que j'ai publiée il y a quelques jours.

Comme demandé sur ce topic, voici une version modifiée de MonochromeLib pour Graph 35+E II : MonochromeLib-35E2.zip.
Les modifications sont assez directes :
• Renommage des registres : 4→8, 7→10
• X-Address commence à 128 et pas 192
• Y-Address commence à 4 et pas 0
• On vire les fonctions de contraste, qui ne marchaient déjà pas bien avant
