Re: what is UA6528P
That's not for 60 Hz PAL such as Brazil's PAL/M, is it? If it is, I'd bet l_oliveira would know, as he tested my overclock ROM on a bunch of different configurations.
Re: what is UA6528P
Over the past few years, did anyone ever get a chance to run 240p Test Suite on an Argentine chipset? Its CPU clock speed test, the successor to the overclock test, has an NMI scanline indicator.
