I made a little update with a bigger font : 10x20 vs 8x8 ; texts should be easier to read now :-)
EDIT : Another little update. Nothing remarkable ; something just bugged me : the font file (10240 bytes) was smaller than expected (10*20*256/8 = 6400 or (10*20=200 and 256*256/8 = 8192) or (16*24*256/8 = 12288 - bigger ?!)). Instead of just reading 6400 byte, it now reads 10240b, so we can be nearly sure it misses nothing.
