Argh, I really suck at this!

Ok, I've been running a few tests on making my own hi-res pack and I'm encountering the weirdest problems. Am I the only one here that sucks this much?

Anyway, I've been messing around with Harvest Moon 64 and I've finally had some success. The problem is, the Harvest Moon 64 rom doesn't run very well on 1964's OpenGL mode. If I run the game in OpenGL, I get a rectangle in the screen area that shows graphics while the rest of it is black. I tried running it in DirectX, only to see that my work (the retexture) doesn't show up!

I took the bottom half of the word "Serious Fun" from the Natsume logo and I just basically scribbled all over it. I can see it fine with OpenGL, but in DirectX, the bottom half (the part I messed around with) of "Serious Fun" doesn't show up. This sucks!

I'm running 1964 with an GeForce 2 MX graphics cards, can someone tell me what's the best way to configure HM 64 on the emu, cause I'm having no luck with it. If I play the game in DirectX, the texture dumps are totally screwed up. They're all green, or they end up as single colored boxes.

Update 1: Ok, I recall someone telling me to make the texture 4x the size of the original one. I tried to fix up the spelling error in the title screen (Natume to Natsume) and made it 4x the size. When I get to the screen in OpenGL, it actually managed to cause the graphics to show up in the entire screen with some glitches. The problem is, the words that I fixed is all scrambled little dots in the corner (where the words are suppose to be). WTF?

If I didn't make the texture 4x the size, I'll end up seeing the block of graphics with everything else black again. I can't see my texture when it's like this.

Thanks for the info, I already have the lastest Nvidia driver so that's not helping. I know the graphics can be dumped, I saw them. The problem right now is that I can't see the new textures I inserted into the game. Or that if I make them 4x the size, it's just really screwed up for some reason. Ah well, I'll go run more tests and see if I can figure it out. But I've notice that the textures don't always load as PNGs. I notice that if the dump is originally a bitmap, I should keep it as a bitmap.

Yeah I know, I need an upgrade, but right now, I want to know what else I'm doing wrong. Like I said, I managed to scribble on the Natsume, Serious Fun logo, but it'll only show up if it's normal size. Someone told me to make it 4x the size and when I did do it, it won't show up.
