When one compares the drivers from a MJ-013R00 card with an ALS100 driver package, there are many similarities. They are definitely based on the same code, it is mostly the names that have been changed.... Diamond put a rebranded Avance Logic chip on their card.
On dosforum.de they made the same observation, of it being an ALS007.
It comes as no surprise, you are right. It's an Avance Sound Device when installing under Windows 98. But it well may be of interest.
In Wolfenstein-3d it has beautiful stereo digital effects like Creative SB-16 and AWE models. As we know even under DOSBox only SB16 setting gets stereo digital effects operating in Wolfenstein. That stereo works with this card. 100% clean positioning.
What is even better the digital effects never disappear from the game on a faster system (Pentium 1). I have been plagued with this Wonfenstein effects sound loss since the 90s: all Creative cards, PnP and non-PnP alike were at times losing the sound of doors opening, screams and such.
Sometimes it resumed on its own or it took to go to the menu than return to game. This restored the digital effects. But I always was displeased with this bug...
This clone has no such problem. It's just great. The stereo digital effects are always here, not a moment of sound loss. 😀
As regards the sound quality I checked the amplified Speaker Out yet, it's no more noisy than Aztech's and similar cards. It doesn't catch any noise from HDD reads (like some Aztech cards unfortunately do it).
EDIT: the Line Out output is clean. No hiss, medium power. Can be amplified to make a good sound source.
The card has a chip that is marked 'Yamaha OPL' and it sounds pretty good. Might need a recording to do but I think I know Wolfenstein music to be sure 😀 Also this clone is a full-width card and has a spacer hole so it can solidly carry a Roland or any big wavetable.
The renamed 'Diamond' drivers for this card are not silly. They create "Diamond Sound Logical Device" tabs with numbers from 0 to 3 which are a "Wave Audio Device", "Internal Midi (OPL3) Device", "Joystick Device" and "External Midi (MPU-401) Device".
They take the best well-known and compatible addresses, IRQ and DMA by default.
Install it and run Wolfenstein, it will find everything without tweaking.
What are the best games to test SB-16 specific capabilities?
I'll throw them at this clone and see. 😀
Perfection is the key. Fatality is the key. (c)
