RMS game save (J2ME)

For this project, you must build a simple RMS file system for a small collection of J2ME games I have developed. Each game stores one of two types of scores: 1) a numerical score (int) 2) a time score (long) The RMS system must meet these requirements: 1) Record only one score per game per day 2) Keep a record of the past XX (global int) days for each game 3) Add a record with a function call 4) Draw a small chart of a variable size that graphs the progress from one day to the next for the duration of the record. Must be flexible to draw at various sizes.
