And if you put in a SRAM anyway you can also do 512K and run Mighty Steel Fighters on a GX4000 without too much effort ;-)

Many of us GX4000 users would love to learn about this mod.  Got any tutorials?

It does not exist (yet). That was just a response to the comment you can achieve 128k by piggy backing the RAM.

I meant that I still see a demand for a solution which does not require soldering - and if that is done anyway you can go for 512K as there is no benefit of adding only 128k.

But it's just a hypothetical discussion (for now).

Attached the 128k Snapshot of the crashed system.

The first thing that struck my attention is that your CPC was freezed when executing instructions in ROM 48. Do you have any such ROM configured?

The memory seems to be garbled somehow. Many places (with typical text strings) are offset compared to my snapshot. There are some data tables in your video ram, where they obviously don't belong.

One other thing: When I asked for the point of time when the crashed happened after changing to 576k RAM size I meant the crash of CPCemu (not of SymbOS) of which you posted the message-box screenshot above. Do you remember when it did happen?

And, another question: You wrote the boot process always stops with the taskbar, but without desktop symbols. How do you get to the situation in your snapshot (garbled screen) then? Just wait? Or open the start menu?

Hmmmmm... Maybe it's a coincidence? I googled "allan blonquist" and he seems to be an american guy that later became a game programmer.

But I suspect the combination of blue background, yellow letters and that particular, low-res font (on the PSX!) must be a CPC reference. Perhaps the new team that finished his job was British.

(Perhaps the font is CGA, but it looks like the Amstrad CPC mode 1 font for Locomotive Basic... Maybe the CPC used this CGA font, created previously?).

I changed the RAM size after booting 128k test and restarted the Emulator. The booting process stops always when the desktop taskbar on the bottom appears and then stops (no desktop symbols are loaded).

So, summarizing the current situation, booting SymbOS from disk works now both with and without M4 (with M4 only if SDCARD is empty) and both with 128k and 576k. Correct?

Yes.

On the other hand, if you copy the contents of "SymbOS-CPC40-MassStorage" into "SDCARD", SymbOS still crashes after the start menu appears. Correct? If so, can you post a 128k (if 128k RAM size) or otherwise a 128k+ snapshot of the crashed system?

I copied a new downloaded "MassStorage" content into the SDCARD folder and it crashed with the same 128k configuration which worked before (the disc one).

Attached the 128k Snapshot of the crashed system.

This font looks exactly like PC CGA DOS.

Setting the RAM size to 576k afterwards leads to a crash.

When did you change the RAM size? Did you restart emulation after that? If so, when did it crash? After the splash screen? Only when booting SymbOS?

Your snapshot above works fine.

Second test with SDCARD empty... and 576k RAM size leads to a proper booting of SYMBOS into the enhanced Desktop.
