Depending to the region you're living, the mobile athlons are also rare and/or cost relatively more than the desktop versions. So regarding the desktop versions do consider this (also for underclocking): Basically you need to check the status of the L1 "bridges" on your CPU, if the points on the …

I have a modded bios installed in my KT7-Raid and it works ok with a Athlon XP Barton MP cpu. You could also use a Palomino or thoroughbred core cpu. The mobile cpu's are best as You can adjust the multiplier all the way down to 5.0 if you need to. non mobile cpu's need modding for multiplier …

So, generally speaking, there are no real difference between those two "GS only" SC-55s, and they are a kind of "must-have" for retro games if I want to have some of games' bgms played 100% accurately, right? Generally, Yes. DOS Games => SC-55. I would go for SC-55 MKII because it has bug fixes and …

The earliest Roland SC-55s simply have a "GS STANDARD" logo on the bottom of the front panel, while slightly later SC-55s have a "GS" logo.  Modules with the GS logo may still be "may still be" what??? Seems the last part of that sentence is gone......

I found out 2 Roland SC-55s here, and neither of them is labeled with any "General MIDI" logo at all on their front panels, which means they belong to the first lot of SC-55 product lines without GM compatibilities. So here is the questions: 1. Is it worthy of taking one of them into my new …

Ranma, I'm sorry to tell you but the SC-D70 was a very bad choice, especially for gaming. Sell it and buy a proper sound canvas unit. I mainly choose sc-d70 for its optical output and its better resolution(44.1/48khz > 32khz), but seems I've made a wrong decision as a retro gamer.... T_T sigh..... …
