[ROM Hack]Alex Kidd - The Lost Stars :Stella Edition
Post Posted: Thu Apr 20, 2023 12:06 pm
This is a simple mod that replaces the sprites of Alex kidd, the main character in "Alex Kidd - The Lost Stars," with Stella.

It seems like a common idea that someone has already created, but I couldn't find it, so I decided to make it myself.

Instead of the original arcade-style pixel art, I've adapted the graphics in my own way.

- Redrew player sprites and some enemy sprites (uncompressed data only)

- Changed the coloring of all stages to look more arcade-like

- Changed the appearance of the item panel graphics

Can someone please create a patch to change the voice when you die to Stella's and to fix the BGM for stages 2 and 3 being reversed?

以下日本語文
「アレックスキッド ロストスターズ」の主人公アレクのグラフィックをステラに置き換えるシンプルなスプライトハックです。
既に誰かやっていそうなありがちなアイデアですが、見当たらなかったので自分で作ってみました。
オリジナルのアーケード風のピクセルアートではなく、かなり自分流にアレンジしたグラフィックになっています。

プレイヤーのスプライトと一部の敵のスプライトを描き替え(未圧縮データのみ)
全ステージの色合いをアーケードライクに変更
アイテムパネルのグラフィックの見た目を変更

どなたか死んだ時のボイスをステラのものに変更と、ステージ2と3のBGMが逆になっているのを修正するパッチを作ってもらえませんか?

I did a high quality samples mod, which you could combine. Can you help get the Stella voice sample?

Hi Maxim
I have made some voice samples.
Here is a version recorded with a sound emulator and a version cut from the original soundtrack that has been remastered.

It looks very nice! Congratulations on your work. Are you thinking of changing the title screen as well?

I had also created an image for changing the title screen, but it was compressed data, so I could not implement it with my skills.

Do you have source for your changes, or was it done ad-hoc? If you have a list of the changes I can merge them together with additional changes.

I don't have source, just a note of the address of the palette that was changed.
Can you please just provide the ips for just the sound changes to be patched into the original roms?
I will try to do the integration myself.
Thanks Maxim.

The voice mod is here: https://www.smspower.org/Hacks/AlexKiddTheLostStars-SMS-ArcadeVoices-Mod but of course that’s still the Alex scream. I was thinking of changing the title screen too.

Basically, the production tools I use are
YY-CHR for sprite replacement and Binary Editor for palette change,
I have never used any other tools.
I don't know what format the source is in (asm file?), but I'll post a working note.
Title logo is in ROM addresses 35d70-35ee0..?

Stella looks absolutely cute! Loved the asymmetric sprites. Awesome work! ^^

A suggestion, which I don´t know if is possible, but would make a nice improvement over original: since you have to play the same stages twice, can you change the palettes of the second loop? Perhaps making night versions of the stages.

Thanks, tsp.
I tried to make the most of the non-flipped sprites available.
Changing the palette in the second loop is a good idea, but may be difficult since the stage palette is common...
