Need your opinion regarding GR8NET capabilities

Thanks to FRS and friends the MSX-AUDIO chapters of the MSX Datapack were translated, they are available on the MSX Assembly Page.

But that is the standard. If a new standard is made, the MSX-Audio one, and some manufacturers releases their ones not following the standard, then is not my fault.
Sorry but on computers I always develop following the standards and the norms as habit.
Remember that I develop for MSX-Audio, not for the OPL1 electrically adapted to the MSX slot.
The problem mainly was that MSX-Audio was not intended for general public, so each one released their one with its own built-in program to use the device (sample and composing). Like a tool for use in a closed environment.

That is the platform one, so you can follow it. If some others made its own version, do not take it into account.

The not intended for general public from the devices themselves. See that there is no one made to be cheaper, removing the keyboard and sampler connections, what is the same, ones with the only purpose of playing sounds. Simply take a look at the size!
Also, I think it is a standard, it even is registered as device on MSX EXTBIO, like the DOS2 memmap. Then is not good to only implement it partially. Precisely the use of the HAL layer (through the BIOS) is intended for what you say, the usage of different chips to achieve the same purpose from each manufacturer, being transparent to the software. Today is the same than Nvidia or AMD for GPUs and using the drivers/APIs to access them.
We can't, and less in an open architecture with multiple device manufacturers like MSX, to look specifically at each device one by one, even if it is considered popular. OK, each one can do as wanted, but by specific device is only a specific way, so it could be considered as private software for private environment. I don't follow that line.

That is another story. In fact, the MSX technical handbook says that you should, not directly, but looking at how the MSX should be programmed.

At point 1.3.

I only follow the manual from the designer of the platform. Is that so bad? I think not.

I think this is some off-topic anyway.

Device received, one question: what is the purpose of the attached cable? I suposse that recover FPGA in case of firmware failure during update proccess but, where is supossed you have to connect that cable? It's not USB.

Thanks.

PD.: ok manual read, it seems that goes attached to USB Blaster.

Ok I've seen that there is a online way to update firmware but, can you update offline similar to Zemmix. I mean, simply put new firmware in the sd card and use PDLOAD file.bin to upgrade.
