Check if ROM is of recent version. Checks the ROM version of this handheld. If it's less than the required version, displays an alert and returns a non-zero error. No alert will be displayed if the alert id is 0, or if the launch flags indicate that it isn't safe to show an alert. WARNING: Since this function is called by notifications, you need to make sure it is linked into your main segment. Definition at line 25 of file MoreSystemMgr.c. 00027 {
