i can still remember some funny bugs. 1. zenkai boosts after using full heal on a saiyan with 5 hp or less. when goku is holding raditz u can level up goku to lv 30+ 2. if u uee a shenron you can "pass" the zenkai level up to other characters depending on your order of chars. if u don that on "max" level vegeta he gets 6 mil power level. without being a super saiyan. goku can reacha power level 9.999.999 sometimes with kaioken. 2. on the first turn goku arrives against frieza final form. u can power up your chars with guru and gohan with moon tail. in the final battle against super saiyan vegeta these power level boosts become permament so that uu can use guru again. piccolo can have power level of 4.27 million or so. and regular gohan has a power level of over 10 million which glitches the power level stat. i think there were many more interesting things but after 15-20 years i forgot most of it
