Re: Apple IIGS: can't reset, can't enter Control Panel

Control-Reset is fixed in current Github (which will eventually be the 0.225 release).

The control panel is a harder problem but I'll take a swing at it.

Cheers,

Re: Shader or artwork effects only on one monitor

Yes, the -video bgfx backend lets you set different effects per monitor. Check the documentation here:

https://docs.mamedev.org/advanced/bgfx.html

And in particular pay attention to the bgfx_screen_chains option.

Re: about Sonic & Knuckles (World)

That's correct. MAME emulates the lock-on hardware and won't work with hacked lock-on images made for other emulators.

Re: Confused about KIller Instinct address map

The "user1" ROM is equivalent to the BIOS in your PC - it does just enough to load a program off of the harddisk into RAM and transfer control to it. No game code or data exists in that ROM. KI doesn't have an operating system, it just loads the game itself and runs. Some later Midway game...

Re: Extracting clean audio samples from DonkeyKong / 8035

Some of the DK sound is synthesized in software by the 8035 and output to a DAC. Some of it's generated by purpose-built analog circuitry that the 8035 triggers. The only thing that's a sample in the ROMs is the gorilla roar, and that's stored in some bespoke compression format. You should look at s...

Re: Getting started

What language did you use for the business software? I can attempt to feel out explaining your questions from there better I think :) There's plenty you can do without even starting coding though when it comes to emulating a specific PC. You'll want to try and find the manuals for at least the chips...

Re: [Q] Externally modular vs internally?

As has been stated, people would mix and match DLLs from different MAME versions and create an unsupportable nightmare.

If your concern is over the size of the MAME executable, all modern operating systems only load the pages of an executable that are actually being used.

Re: Automating Robotron Game-play

This is best done as a Lua script - there is one floating around that auto-plays Super Mario Brothers and Super Mario World. So the good news is that it's possible :)

Re: Debuging game code using Mame

There are no debugging symbols in arcade games - the best you'll find is sometimes they accidentally left assert()s and debug printf()s enabled, but those are both rare. You are reverse-engineering the game from the assembly on up. This is how MAMEDev figures out how the hardware works, most of the ...

Re: Mame remote API

There is already a port of MarI/O that autoplays some Super Mario Games and attempts to optimize the score as a MAME Lua script. So that kind of thing is very possible.

Re: Has anyone manage to extract encrypted Naomi M4 bins?

The Naomi encryptions are stateful and depend on a key passed in by the program (as well as start and end addresses passed by the program). You can't automate the decryption.

This is the fourth place Spottedfeather has posted this question, and he's going to get the same answer everywhere: "MAME2000", as you might infer, is 17 years old. MAMEdev generally does not support stuff past about 6 months old, and we definitely don't support third-party hacks. We can't...

Re: How to ask someone to add a new Hardware to MAME?

Hi! I'm the MAME MIDI guy (I implemented the low-level interfaces and most of the existing hookups). It appears all of the common X68000 MIDI boards use a Yamaha YM3802 MIDI interface chip to do the work. If I can find out how those were seen by software I might be able to do something. Thanks, -RB
