In fact lacks a simple engine to create your booting.
Examples are all based on the "mcs bootloader", to make their own, have a lot to clean/remove from the code is not correct, but because loader should be optimized, then it makes no sense to write in BASIC. According to this lack of finished operator/function for writing flash program memory.

ps: do not want to write everything in assembler. Confused

maybe it will help you actually have a look at the samples. there are already asm samples which do not use the mcs bootloader. and these samples are just a sample to give you an idea what you can do. you need to adapt the samples for your own goal.
if it is not correct to remark or change some code you can better find a new hobby/job.
