Hi Kroah,
First of all, congratulations and thank you for sharing your work, since a while I saw your site and since that time the idea made its way to me to try reverse engineering.
Sorry if my english is not perfect, i'm also a froggy , but if this topic can help other people, it's maybe better to be in english.
By curiosity, I began to look games of my childhood (on atari ST) and by challenge to try programing remake.
Everything started well by looking at different forums (using IDA, steem), etc, by putting me a little more to the asm and also take a look at hardware of the ST, but now, I am at a step where I do not feel able to move forward without asking for little help or advise...
I began with a sport game, maybe not the best idea... I take a look, I have find and extract sprite, background, etc, find main loops in the program (display, palets, way to do the scrolling,...), piece of memory where stock datas as score, players data,... Not bad but I'm somewhere stuck, I don't know where looking to continue, do you have tips of the variables / piece of program to look at or do you have special tools ?
And also for remake, what's the best option / tool, i take a look to unity thinking it'll be maybe easy, but i think it's like using a grenade to fish...
Thanks in advance
