gameshark, tekken tag, booting

[shrinkwrapthat]

so i went and got nba street and extreme G racing.. burnt them.. made a couple diff. copies of each, patched and not patched, im still kinda wondering what patch i should use when there are like 4 diff. ones to download... anyway i get to the screen still in my gameshark and it just freezes up still.. does anyone know about the no solder v5flex out there? and could some of these thigns cause it to lock up liek that and not play any burnt games?

1. bad chip
2. whenever i installed the chip i messed something up
3. im burning the games too fast
4. the disks i bought at walmart are too cheap (DURABRAND)
5. im not patching the games right
6. the gameshark i bought is messing up

please reply with any info u have... thanks
