Well regarding the font for the M3 card. I was thinking the same as everyone, it's not the best.
The link to the altered (menu.eng) is not working! So I took the advice of your good member
regarding altering the code for the (menu.eng) I altered the code using a std hex editor.
I found it at offset (00193150) I suppose it may vary! And it does indeed work.
But let me say it is better, but not brilliant!
I have taken the liberty of making the file I altered, available from my server. If it help's anyone!
My card was a M3 Real with system software ver (4.2d).
Please try replacing your menu.eng with this one, see if it work's for you!
